alright,　hello　everybody 　 welcome to day 　 two forty four con uh i hope you're all feeling at least as tired and rested as i am um so yeah we have a did know i last so i get the be are by all right so a today starting up we go fill posed i or just one a so a cup of things first lead uh and uh you know the sponsor's of car a not a long way tool subsidise the cost that a k. it's please please do c. than to that please make the f. that to go to of the around a tool to the all um and grab some three basic the go them i mean the uh and tag d. in to disclose and um uh the uh the thing is a we could do is you know we we were gonna do this sex chip we want to know more we could write a what we did on which speak as u. like which speakers 　 you didn't we have said like forms and feedback forms please fill than it in so uh uh without further day head is fill go through i more than so today i wanna to talk a little bit about uh u. s. b. flash tried lower an say it's uh some of the stuff we gonna talk about to day hmmm their remove late well the talk about the basics so u. s. b. c. e. v. surely everyone also us so we're gonna relieve you i talk about uh flash ride little bit about technology in flash tribes a a every one you is on some live you have them hanging around your next i talk about uh for in sic issues that are specific to flash tribe this is and then we're gonna have the real type about uh follow of it microcontroller what can you do on the cheap we had last ride i think it's deep just likes them me and i really with hmmm better all right a it if i can right of my you guys at probably more or like lee saying the show what then people back a menu acts the i t. crowd a a a have you tried what uh i are three are a i'm a each are or a a are in or backed up again i just recently discovered that show you know what we've left a as a the i and it finally a of talk a little bit about up a tension probable they it in let bro it in a to try to do some of a stuff i mean a talk about uh and uh a some solution in the i i came up with me i might so basic am you s. i. b. a. i u. s. i. b. uh out will talk about just re a be are so we will bit about a hardware and software so brief history uh a back in the old than times some of us sir or wear are these all than times before nineteen eighty six we had a non universal serial bus everybody a there own special eyes for us um things were some what news in a a new ad the can figure sir real port's to uh work with every single buy c. uh a different kinds the cable's possible in need discover it all no that's a on a normal button me abel that's the different kinda cable and stuff but more their in uh so in nineteen eighty six they came at with the u. s. p. u. one i in the wow to you to connect things more easily from the other's perspective a yet speeds of one port five for twelve mag and that's for sec at to years later may said uh we need to weak uh uh you as screen one one was board hmmm or in to years after that he s. p. to i i am a uh at an a new that a another screen call a high screen it than and a you hear is go buy an a two thousand a they've released i the u. s. i. e. in three point out was fact an hour we have uh at a in surely a up to find it a bit for second speeds all right so hardware embossing the hardware hmmm yeah ideas pretty simple for wire connection you get to data wiry is he get up our wire a ground wire and uh it's in that is so that uh a came a lean more probe ad something improper or right uh which is a go uh the to for me is or perspective it's a bad for matt a develop are first act if if you have have the device that's all ready not a couple we'll or it's of a and it's not a of court can to one and then you can insert sense or tree for a enter change or are or you can make your all or the and the take give or a complicated but i can me a work and eat is a purse but i could very very simple uh everything's ha ha the more he is is different role mall the instead of apps on hole a uh less and always sensitive and you can have a of to sixteen for cable is right so how all this since get stuff a i'll off a a a while is you want something that's automatic and that you don't have to worry about i set in john purrs and the way in this works as or a process call a name oration wear how was hand am ice as talk i mean char their an figure out on what's to to one on you what they provide uh um hmmm the stacked a has a number of standard device class as as so you men are faced the vices print or is audio and mass or each which since the subject of the stalk so i are oh enough about the basic stuff musically flash a lies um time i well uh some of the things involve with a flash right answer you know what is the harbour are local i'd soft where let's or a file system as white one expat uh i find it and a little bit with how a windows deals with flashed right so if your is a cake sure i wrecked it off or a what can p. u. d. a uh her i all just say that a right up a a oh eight tape put coal flashed right of to what do you had you have that contract or i so a you have year u. s. v. a. a. connector hear and then you have a circuit board the biggest thing on a circuit board is going to be of of flash memory uh i'm and stat then last right so oh typically you'll have a flash chip there as a particular one picture and uh as a it's fox for east second oh why i as a a for it's is not installed and then you'll have a control or at some or so uh all for a know have a a so wait or or i usually twelve megahertz but a so it or crest or if your lucky an this is primarily on the old or the bias as you get a read rights switch we will talk about this a little bit more or by eight or but today typically don't find a in from any flash right should be in what that's switch is kind of unfortunate and i if your lucky knew you get a nice little l. e. e. d. at that blinks at use so of that you know things are happening um yeah i i have a couple of flash tribes he i including some for gigabyte drives i got it might will call stables for or how one pretty eight dollars a one for jewel eek for their were only dollars what there's no flashing leds cell it you don't you know what is going on one this hmmm all rights off for the off or to pick loony is implemented and firmware it's i to special eyes comptroller chip so their are are the number or manufacturer's that put out these chips you know their pretty generic the i i you even in and flash memory they talk q. s. p. right it's so what sorts of things and watts that you do thought they have to detect any kind of communication that n. to the for i've they have to respond to standard brick lasts so a sinner quest such as hey i tell may what you are please use a spend yourself please stuff suspend spending are some things like that um may have to check for errors in transmission manage power uh in devices or allow lower you request for are for and bubble of power and if they need to respond appropriately and they exchange a town corpse the file systems what kind of file system can you put a on this flash right well a let flashed try a presents itself uh to year computer or it as a in block a vice essentially try it that emulate a hard drive and that says a high um a hard drive to quickly uh a hard read that has a bunch of five hundred in twelve byte sector's uh on at and you can do whatever you wanna any any kind of file system you can put on that i almost every flash try be everybody though is for probably prix for mad at a width that our fat thirty to more likely fat thirty to but um it's sometimes you will find i dry ride that's format madder wood the n. t. at that's i now there are are an number of uh flash specific file systems or you get the true flash file system of the extreme flash for all so it's stung uh the journalling flash well so still a one am i favourites is yeah it's yeah another flash file system and of porsche you could also put your favour unix for a linux pol sister you can put x. to for ex five whatever you want on their are by or um file system which gerber you prefer can so it it presents itself as a block to buy to you it a free flexible on and the how you can connect uh so what's a talk a just a little bet about windows how dozen a win does respond it to do you flash tries so we'll talk about what happens wean you can act i i drive how did you could bloc a white operation is a p. don't have one of those lovely switches and how do you figure out uh who was mm their are you know why uh has min the or we non u. s. p. d. related to find your computer okay but the so we here is what happens when you connected rive you know it all seams very some for right any u. plug it yeah and uh and you could a little norway's right c. plug at in you get the little noise i must be easy right uh well uh if at you could begin to there's my other way in if you did involve and their hole u. s. i. b. what's one and in used star go all in the ice as a get's so little would dick d. of and i i think the reason for that is that it's a there's twelve st　 in a i don't know if you guys had twelve step program is here for at it it display split it it uh i'm guessing you do so do he hear are that twelve things that happen you can act your device the harm no which is the pisa of four rare run your p. e. c. d. normally uh their is to sides in the u. as spree e. there's a uh slaved or device and then there is the hope's a side so uh the the p. d. c. is normally an the house is a a this it at texas that i ad a wise as bean connected and the hard were at the harm and for form do you a whole was usually it p. c. hag so what a connect an something so then the u. heart little charm ends what a kind of capabilities this device has and how do in in do that uh it's n. is a bunch of signals and i he know and you can i do you can read the spec tiff your role the interested but spends a bunch as if a sends a but just ignore as and it determines half fast ask and this device operate can to deal operate that uh one point five megabits per second uh we're can our parading it while mm to say you erm ends that beast on wear these also so what resistors are or install on the device a so so once it's to try or in that than knob says thank if we're tell me about yourself uh now re set i sara sat's to eyes and then uh it's says hey i use say at dick a do in twelve mic the bits per second kenny you knew for hundred may be and the we act an is zone for that as a little different at they don't just use pull what we're this true as it an part because a backward compatability are you you want your device to be back weak and bad am more or to or you as we want ha so i would it does is it's sends a bunch a signal's cultural or c. then based on the responses the de but you know it the book in they revise mice responds essentially it a power we a i i i know what your saying i know how did do i i speak i you wants that an all on it is that was is a signal i have uh a signal pad it is a uh was set come to and point's an the ease canned points are you used to communicate in the device in the host so now we got communications we've established a be mm yeah and all this and laugh to be dull and is to figure out and what it is that uh hmmm does the vice actually dot so i that a ask for a disc richter in the script or is there's a a hill site of descriptors available from the device the tell as that what is the maximum size tack it that you all take once it's done that and at sign and than it a dress so as you you be device an vote if one i most likely if you to the first device and then it's gonna numerator three there are capabilities once since figured out i'll we your uh i human interface device for you were mass storage device windows is going to load an appropriate i know if i i device driver so if you have a standard flash drive yeah if i have you know uh hmmm this is a little sigh and this kick i draw i at buy five have patriot memory whoever if i had to some money also as drive we're knows there's a half to have but cost and rive are for everybody is dry the all u. is the standard interface try now some drive's might use a uh uh a custom drive are get in particular if you get encrypted rhymes i didn't bring it a with me but i have a a flash ride the aches to fingerprint kents i mean to sings beings like that is a um technically what they do there is they have their own custom drive or or a all lee a a lots with the finger part which is really annoying if you like to run it when it it's because they don't poke provide own linux extract are or for that but the uh i mean it is attach it and i finally a device can have a more than one configuration available of most of them don't as a bit had specially flashed try to to be coli we have one configuration and then the device exit this is the configuration juan an a u. have as is all right i very sample write yeah i make a little noise you plug an and that's all that's is going on a p. an and this c. it's all right as a said before i paul off the end which you you want to the lock of right operations to hint if you'd lucky you have a little switch i i your dry me don't see that a so much any more unfortunately their here is all work around that kind of works okay if i re one of to the lark a right access to a yeah i'm marie u. you s. p. device at that's the downside i i i can save well i you can write to that one you can a lower right in that's one now t. yes i could right software the it ex a different devices yeah like you go all about at that way it but if i one a do it is very easily i i think an one to the right just rain it's it and i i kin fine in this g. v. under a local machine to system very control so i control's door's we've ice all it's a used right but to act uh than all i have to do is crete at key if a doesn't exist and put a law in in now i can't try to any u. s. to be device hmmm why what it want a do that uh i maybe i i work in a a sense at the uh a organisation and and i don't want all of why employee is it's dealing information buy plug a in their a flash rice thing take in them how all to buy the way knew my i preferred solution for that uh this call the a a glue i a a in a loom then you huh as gone you port's it does wonders um you know see a little weight or i i have does in want for ha do do a uh um the comes in a a in t. for then any final i at a you uh other options you can buy a commercial white in the lockers thee cheapest i schmo or or or right walk or i was the able to find it cost to round eight hundred lee ass um uh as the cheap as one but i am gonna show you some thing that you couldn't bill for about uh twenty five euros twenty five euros what five hundred euros i at are just a waste to make their are but the um and i we'll discuss at of bit late or by the wait how the reason is you might want to right block are not i'm just for for n. is ex i if your like an e. e. u. have some i flashed tried as that have the all of your grade tools the your were to way is right uh i'll a may be it could time a i'm sure are sort of will do you for fort of could on not great to war or well what happens it if a am walk to run the university and i i wanna get some to a hold am my flash rides like plug it the an and and i forget what's on the draw i if what happens to me a all lists so no we'll message cops a uh paul the university a a an die a buy since to tech to do or a little mole less just software or mic tools on this flask ride or on what is a gonna do oh hi i am hell held a for we deleting the um for you so it know the the and then their time's like that were are you wished you had the right protect which are something like that uh so i we'll talk about uh can that all right when do it is if you doing windows forensics window's it is in glory to get storing of all kinds of information than the reduced rate a you guys are probably all of where uh i'm the as your average user or is completely oblivious and he and the moderate at least sophisticated user or that things to you all if um need to leave their files a little better probably does in in meant think about the little one of the read just cos as a carey place for it's nobody wants to go of there so uh is and the registry store of that i'm marie east saying volume was the u. of ice that was at are connected i can all kinds of them from a chanel bout it we i think a more to a a d. you that do day in do that for forensic investigators well maybe not uh uh they probably do that so that in one i plug n. uh on draw up uh and the bi is the second time it's a little faster so as hey i know that de ice i know what to do you yeah last year or i a one a uh the cyber forensics class had the university and i i did this is simon i thought this is gonna keep my student's busy for a couple hours i said a right i want to the go in this computer a web here at i want to do tell a about every in flash ride that ember or bin the one in to these device it's well i've have am in it's after a de in this is i'm and i thought oh okay i i got a couple hours just kinda kick back an all acts one load it it at have one the do this is set it's saying there any are read everybody can i just uh go a go be a you go to get to i tame in old you was me tell have you you you i yeah and hmmm boat lead in and you a all right near is that air is the uh all so so you will more i uh is a i i an mean you fence uh of this tool u. as b. they have do you nice little to and a um it it'll show you hear is all the device the is different i to see that i've at it sorta by it i i a you can see all the uh so you with interface device the tsar i'd can add at the may as tories devices i is the currently connected what's the drive wider are are a line to it last time at was collected in stereo number is you know create a day then you're i d. product i d. firmware immersion and you know one kind of you s. to be an a device for was it i oh all these lovely things it'll tell me you do is on an all on an all non an ah uh so something the keep an mind you know next time you know in the movie's what happens right then the movies somebody you can ex their flash tribe in a download the secret information in and then de you get i a get me busted later flow had at they get busted later okay well there's all kinds of air or from may chanel their are you a of them or all this story this a just stop on windows what well i i still i i would see this a this somewhat a but only slight thus is the what it by that the all you know a uh to we mice to a your thank it all of tools gonna be really mad because you know we all of this stool to do this i thing in find a minutes an i you know feynman minutes late i'm did an all it u. port's mice in is they one all were or i flat had a a k. a is a one month class b. a not um i thought well that great because their were in smart nat were at all right in so i would what actually was kind at we use do and surprised that they i the m. in as to do that are so stalk a little bit a but for grins excess i uh and we talk about for l. jig eight c. you a on um others such is hear wrote yesterday the hmmm pulls what forensics as you know vest against a a new jean we uh port in the crime all a best a geisha and not always nope what um i one lee what and a flashed rhymes we can read a i there are as a memory or uh as store in to media it's so won't we look and a flash tribe s. memory typically flash strives a use flash memory to role their different kinds of flash memory there is a no more flash memory and their is an and flash memory sounds ca like a or and pay an a right end in birth for is to of the way that uh of flash memory as accessed i nan and flashed memory by far is what we gonna see you can flash rides because of speed but primarily because of side s. all right in and flash trips are a much smaller what this some of the down sides a flash murmuring uh hmmm do you can only right so many times to flash memory typically about ten thousand times after that uh them memory read the great it's i it the you had issues all there are thing this you most of these chips are are even close to high speed it for hundred eighty make at that's per in particular if your riding to the there are no work los um blue one wait late or when a show you use um for an the vice as are you all see that uh their rim limited if not a by in them do a by a is foot there limited by the flash right the flash rights can only writes so fast is still it what really kills me you can get a flash tried and uh some of the hole even have at tie support us uh i speed okay i i hit does so it a for t. it a. but that doesn't mean your gonna re knee u. it paul on or of that shoe a a at hi speed race yet all so a means year strictly not gonna right any were close to those rate you know a in in that a right it well may an that's per sec but but that's good ember thais to i just a poke so um other down the sides to of and flash merry chips you can only right champs you can try write and one the a little buying so what happens if i one in change a one little buy a to i re uh out an chunk i change a one little boy uh and i put the back at the chore it some cases the chunks i is it's for the read in that will uh in the right art the same either a a lot at this this handled by the control or or yeah eds really crazy i know a we'd i raise lab n. at may hear in at no um so i do you know i are a t. a reading or riding in am blocks the is a cindy before typically those blocks are five hundred twelve bytes um some of the new were rhymes to you you have a to k. a. i i uh a sector sighs as or may be if for k. i. e. and i don't think end to ever it actually c. you a one i i just for at the day exact stick you know a it now i had some large ish like thirty to d. egg d. flash rhymes as and they still of five or or an twelve hmmm bight blocks which is horribly inefficient especially when your un in fact so are at thirty to but it other the things you can do you thought if you have a flash their are the vice i in it's fin damaged you know yesterday dear rose sure the some really the m. n. or dry ads uh up if you have a high d. a. much flesh of i um you can you a normally somewhat easily on the slot are or that memory chip the a long as them memory chip as an bad get another flash in uh uh the buys and i solder down on their read at uh a you don't have those issues that you would have of the hard drive who are all i'm sore eight you know like the stall a hack are or all that uh for in circuit board just just a period of an sorry so so uh if your really what key hmmm you might have an g. a. t. tag ford um for those are we are familiar j. tag s. a standard for testing a large you to connect it to a device and do some casting on it hard are other thing that you should be aware of uh i you when you buy a hard drive as the each she the little bit right he buy that do you combine may are or at the tera byte dried on it does a really have a terra i i it has a you know a trillion bites not a thousand twenty for done to thousand twenty for except or right so the you can i i have sliding differences if you bye a of of flash ride you should be aware their can be slight difference as as well i mean oh i saw my all those control or chip so i talk about a little while ago some of them have their own a or a um and there are all of the storage and some of them steal some are a your flash memory so you fiance the flak as is a a for d. egg get flash rhymes from the different manufacturers they might have slew white and lead different amounts of storage which might he bad it's say you were trying to make a if or ins zig copy so i'll the large or one to the small or one all right so this some thing to keep it mine all right uh i i as this story to me the a it just emulates a hard drive to quickly what a scuzzy interface then as a said five hundred twelve why it's is that typical sector size um yeah off an all use the scuzzy you is uh uh i and then a to brake we are ah uh a hard are flies try is form mad it as just one big partition part logical u. we that uh a need flashed rides to can import a multiple logical units oh i i haven't heard a um yeah i i here treated differently in different how s. it's in fear or we we windows can read it all there are than the first of logical unit i have am never sing in that happen now maybe i'd i have n. user a persian the widows but typically i i can height information on hi are logical you'd to is right to if i had them from a should i don't want some one to just naively get a light clung in my flash try bob hi just i put it on the high or logical unit now for a really pair annoying well first all i i a carp of course i'm right in line act's right if i am pair are a than knot run do windows but oh i do you can use in the crypt if file also is stuff and put that uh on a higher order or logically a act when your flash reich to just to what tip for this stuff that you don't want just a purely in or people look in to are um uh all are things you should check the demise will reports fits sizes and that's true and has the threw real size okay do you there half to an in um patch all of some really she a drive's come an non a china are this was a few years ago they would have our thais them solves as perhaps or of for gain dry and they were really a and i guess lay figured that a it'll take on while for or some one did know what is you know all this so i mean you get over a gigabyte and you get all these it error or is okay a keck mic an it white ten it can cos it's not and they are they was a lot i i now r. right and um other things you should be a where uh um the four you be uh are you know to uh and the hard right d. m. in a. m. u. know uh at the house in is a al's now uh a thousand twenty four well you might fake wal since we're dane wood memory or chips when a cons to flash drives we don't have to worry about that uh all ex not quite true be uh is i'm and to things i already mention that's some control are chips you use part of that memory for them cells than the other thing is you need to realise their is a a error correcting bites do is a bout sixteen we lights and for a five hundred twelve byte block so it really takes a five out or an twenty eight bytes just or a five in or an twelve bites so you lose a little bit oh okay so let's get to the real flat or so i have a little fund with uh i'm micro controllers um you the talk a little bit about uh did chip choice that i a for make in some devices how to we talk to flash try this how can we make they re small i one a claim my have the world's smallest forensic duplicate are um you can challenge and me and that later um okay and i i am but this slightly larger about but the more user friendly version and and then a talk a little bit by i you using a. a mic for a controller to you and the wac right operation as part chip choice i chose they think oh loan to which you have from f. t. d. i. guys a were her of this company but a little north of hear are the it could if it glasgow i think it were we're at a for at on uh they do a lot a you s. a b. stuff but i an am an error hurt of a are do we are the little chip's that make your are doing on talk your you p. c. get so make pose gypsy that to do a. de uh all right their scene to be the u. as p. e. people but they deal it they do it a that's probably had at some thing to do in you s. spec uh but well i guess they get our it just building owes chips then nice idea yeah ron's cat or are all like your controller but a make one so they are introduced the the ceres this is the perspective in version of a serious and what is it features all right you get to false p. e. u. s. a b. a. to go in out all interface it's i an you can can figure i am as either a house to re is laid it i to wear are a t. six k. a. l. flash memory that's respectable sixteen k. if you are a am it's down as low a p. don't you microcontrollers otherwise your are like al out a pretty good um and they have all the normal micro controller kinder the stop right a also comes a that easy to use i d. um some simultaneous facts us you can do you between devices a are the have a different or and development module's available ah a unfortunately the only make sir crux mount chips i don't know how many v. you a why of to build a lecture on ink some liked to solder i don't know to many people that why to start or was surface not chaps right it's it is so of uh a bit about hassle an particular you have to hmmm make a board right you can't it just well i've got this chip clean billed something wear that you have to make a board in you know hmmm do you all the edgy in they can be a little bit an all so fortunately they do do you produce is some development board which are sensual aegis austin their chip uh with the but bit a big a okay hit now i get a it's like oh all i can pluck as our a bread board now so we use your deal ah the end those the by suzuki of element bore are cheap an all of they you might just instead a just bright boarding net them my just plug an in to than actual device which is what you'll see here to but so they have the a as i i said servers there out acta jazeera ah are here's are a block diagram am know ha are a how well you can sew you the spit in this at a have a little and that it c. p. do some flash memory a a little bit it's that talk to u. s. a b. and then the can a skin are micro controller stuff general proper sigh oh that's a p. r. i. if you don't know what s. p. i. a as it's real common thing the use used a top between my crew controllers in device as it say it's i to uh of but to um i do you get ask real more off not that later well i'll there are i d. v. a. is it bad or uh what's is kind a like this this is still one from their are brochures um mouse so you the actual i d. here are you that and you know t. a last are a a all what a what he think other as i i d. and set well it is not a collapse buy i it's is not so c. an all it's very functional i i i've had an worst um then yes sits not because clay have sped uh not building in in large operating systems are anything like that either the fit in might to hundred fifty six k. a. m. i flashed in a it's so uh i just as a up of but a project hear this is actually on on at come non on there or as as the a um but duplicate or actually but you know it uh a free basic out of it an the uh_huh the stuff he would makes but it we you can ad it your co ut and you get nice to do is an set break points in a sort of the botch it is in excel or exact a a right um another at nice thing that they have the is they haven't no i you general purpose tie i over on the chips yeah and you you can and said that are a um an ice cue we i like so that you been use real ad uh i an ear as one of their development package it is all right this is a a sixty four o. he a. in in are and um they have the three merge is in is other their chaps they all of the same functionality it's just a different levels of of the a high all thirty to pay and forty eight pet and sixty four pay all right cell this is a belong no this is not actual like three or it you know mark it on a of hmmm a six c. pork pay a. and we version and um did you'll see then a actual one here in a well this is actually sighs well like that okay and lee also make a smaller such is thirty to and you'll see that a short that uh i a hear is a schematic for that uh development word pretty much it it's all go one on here they have a be in is for the chip and then there's a couple connectors to do you add b. stuff all right so my first project i said uh yeah i the or one on they make a nice simple duplicate are or just some new a you can i he you can make or forensic copy with the sector by sector copy you you're you set uh and mean certain your draw i've to cap be insert the target drive uh uh ideally the same a tall uh me talk about the fact that it should be a uh in least the saying sighs in might one a check that hopefully use of the same locks eyes not or problem their but ease c. is to be using five twelve and then do s. sector buy sector copping well because of them like a limitation is on a flashed tried to and this does a very a little bit depending on how cheap t. are it takes some about a lead them in it's to do would gigabyte i i he so if you have a for gig drive forty five minutes your sell maybe our it it'll be dot and it's kind of a pain hour payee late or uh i the you are are are do you pay a now buy making a i do you put cat has it flash strive are you feel eight or or i do when it then edge you which might be fast or but then you working with the end then she it's gonna we slaw or mort may be you actually just one the make a copy or may be you wanna make it copy of you are can tie on a drive or you know when you want a do a sec to buy sector copy a lot to make sure that the new one boot it's when you'd done so high do we talk of flash ride very quickly uh and use as mole be called all only mass storage your sometimes call d. b. e. b. a. because than they're are are different heinz a transfer or as their are will out but a lot it devise is use the control and pointing in this is to control their are transfers all uh all lee mass store is of ice and you'd not they use the control and for instead numerator and then it everything is done with ball gag and points i so these send out stuff for you have three phases all right there is like can come a and bloc out of rap are or that at and sounds like it must rap it come a and i bloc possibly sim day to transport and then there is i coming and status rap or are they comes back and i pretty much all these drive's user reduce to to scuzzy sad and everything is a said is on board in points hear is a little so you code for a command wac are apt are or who is a look alike uh you need a we start out with the signature or for their is a tag or tag as use a so we she a in this command blot i hmmm wrap her with the come land status rapper they comes at the yeah so that i know which one i'm talking about uh how much of data an my get this and and he flying zits it the inter hour so which logical unit is that what's the leading to to the link it is the link the i come me an bloc right to how i have a sixteen bites and i'm gone need use fee wean six hand sixteen right the smaller can be and use is six so that of us a so the command line as is said a a six at a sixteen bites the for is why a is the rim me and so for example of that can me a a and to format your draw i've you which is something you might one to do because it's quick an a at a a miss u. is do you you we'll the for mac and it's a lot quicker they riding zeroes to the dried they re so uh thing eight know the uh operation coat for that i one want or is for you can tell it which we we i on you one it's um if are thing's get a little weird because they don't hmmm i at and or retail in on bide to boundaries so the you m. three d. that's for the logical unit number it extra parameter is extent are to set are is set right their is an example all the read it in i ca me and line there is different version is of this this is call a re tanned and it's gonna have a poet of twenty eight act's and here at the different for amateurs i won't go an to that you whittle bit one the different time of but i jig hmmm here are some comments guy's you can me endless this the jewel flying useful one of we the most every the lines what what m. am at the is us some of them my him a listed as we wired to that's required by the scuzzy stack so you'll note is format and unit's required thing in or u. are for a sick lee says at i only about in the eyes and what what's so i just says this is what i one a use to talk to you and then their are different versions of who re eat it some of a which are required or and re capacity it says how a big are are you re for mac to have as to ease is how much from and real space as you out after you ben it for may hat had a in then of course we have to be able to right and uh there or coming ends for things like synchronise can actually cube an caching in and i one a on plug mine device plea least sink it so that i don't have a date to props in are date a las right i once this says bean's cell and you have a come and status rap or or they come was back and it's is much simple or if you have the segment sure that ad in that as soar she a so it would he you re eight a command bloc and then you you can get a raspberry where as the do with that l. as you what's the difference between how much to ask for uh an what you got and then more or uh most important you have the stats as of out a three statuses are possible zero means hall everything's in good we why the main so everything's not get good and and to go means of phase there air you i think what is that main um i don't have and time to go into it right now i'm but if you're interest at wheat i buy or later bum uh i a there you he a use may ian e. i just say and and am and is in a send information on me you ask do so i'll use a busy road a to one and they go back an for it in their rules or thing going back an for it a as to wear your toggle me i d. give it d. the run and zero or one and if you get out of phase then you end of phase ear are which means of okay i i'm not sure were we are uh to go back to zero hmmm bottom of a reasoned men it's just this a simply a one it's historic all a scuzzy dry n. sick the in your thing in your machine you just one a check for a zero or checked for a zero all what's one on and then you went wired to see what the air or what's it is a lot of after then the same is it is zero or is it is is is that you know sometimes you just one an know from work or not okay if it's so well i i uh just a a little bit a culled what are i uh you know the here's uh_huh cover would that we will can act to to eight flash try buy u. bolt storage device i using this chipset uh i of the an very briefly you or it are imp read if he and all to of ball to buy a. sea d. the said up a bunch of variables u. can act to it a in a say hey i i wanna talk to it mass storage device and it we one that speak scuzzy please lay all do with and of the pore a call will be the is borg only mass storage for to call we been talking about and i want to find a a device he go all who buy the class which is one i is specified hear uh i'm a an high o. control call and hopefully at the end of the stuff i i have to hand on to a device so now they have a handel lube i so i i open it right chanced to it it's i the might seem a little we are dwight do white old been and then attach of that that's just the wait to is um so another i uh control of or is the cursor sink to disappear an this room i think it's a bermuda triangle or something i don't i know what is not just me because the other oops so in once see the curse your the in person they are or do this a or uh um ah or you in so we attach ten once we've attached we do some stuff and then we detach how do you read right actors theirs the stuff uh for a bite in the library again one so i have a hand do as a ice i tell it which sector i want to and right t. ad should and light i i was wake it for speed to pick up day and do on in all right pair lee i'm at that like a so you to you know off we go oh n. we can read in a um i just sector's not a a one thing you should be a where i of it the you to doing this kind of stuff you can read em men individual sector many on these de buy says of like to read an riding forced or is so if you will are a t. the end in one an sector are in a time but they really have else plaster is that their working well the what happens it is if if i read in it's sector ear uh or it gonna read in the first cluster and then one i we'd an sector juan a it is gonna read at cluster in again to a again and again an again all right so to uh and that a in pretty slow i so you one of try not to do that right now here is glee lead the vice realised that i i have to do apologise i i know the in this country you have an in version in to the ladders so i've mean polity eyes are if my usability or to see that's if ends you i would it a a right an apology hmmm but if i i apologise didn't riding that might to use another z. e. uh and then you the in a the head dost like oh continues self all right i um uh i just so uh an order to improve performance over the simple minded weight of doing this but i i implement a uh double buffered multi threaded um in hour wear them for this i uh rakes peas as the device some q. i actually use that for men you you know in and then to tax stuff at all zeroes cos of off for a and most of it is empty why should i were i why ride zero as uh or the i'm it doesn't make sense and this context hard eyes and make a or sense um an it might suite things up a little but a the for it this particular device so you use the smallest uh the word that the eagle on makes are apt to the i. ex yet i actually took what i there development more it's and a have to a a little bit fence side or directly do the board right and it's or a i tea bun ford a i hear is uh no a you can see this is a. i i hears a for uh here's a actual size uh know it as i have a convenient to care or you k. t. and uh i help with the on in the the i so you know here is a actual boat to or it to is so our small i dropped the know it is the uh um actual uh the buys based on a thirty to pin development module i just a on soldered in the uh oh and is in the of ends on this is and side or buy leds in my power connector direct a to n. why it a and are at of the pail is mall most it because a were all a me in might pot it before i got the key it's i'll choose care lean tan or fight i this to a how what do you how our so i of the ice uh are well it's say u. was screen advice as an art or so then actual a you one would have to get a a u. s. is we you at our cable to power your u. s. p. device a i makes sense by the way i i and this cable air we claimed off from might bro in we recharge are a to id fit when bad that thought a can so nice cable i can do something with that uh so uh you you know part of the wine u. work might wanna to do we any of this is to all a boy it have to use a computer or what gone a compute around the do things of nowadays an so i got my t. enter eight tad have what the only thing i use my computer for ease per gram it in things like this oh no but you might not i have that new might be travelling so you might uni in in to be some power so you get or other al help to way it gun tail and do you know the and that has put a little the a circuitry in a couple rechargable double a. batteries are little bit which juror three ball to up to uh why i wall and uh huh each plug be the and then you get power okay and this guy east bring so e. he's peaks blink t. he doesn't speak english east int not american english are a british or in the he speaks blink eat and a bring blinking being he plea is in are your original cell i can grab a drive over here hmmm let's see what happens wanna from green blink do you a yellow blink eat are what do you thank he l. a blink you'd maine's hmmm i mean blink nice blinking scholars are in air blinking yellow blinking means pleases or or do okay a hmmm your your target the mice all right so are now i is on a foul an yellow are a hand it you what i'd bill see blinking lights hear right indicating acts as in overtime i even a you will see these why it's sequence a very that s. am i uh c. you just want to the next el u. e. d. every couple thousand sectors i we'll do that okay that's sits waive say if i'm that that and they okay and then one it's don rad uh i know is probably a batch oysters read it a i'm i means i'm done now right so well uh it that lee is not a he is not of a in are yeah in that the on so that's why one small as now you might object in u. might say well i i should that's that's a nice fill but and be i could you use a little more space and so oh i maybe i one a use am or user friendly i interface i want is the same co as and lazy good programmer's are always lazy so me model meant the blinking lights was some english i also like the power over we may be what a nine more batteries and i you know um of make a little some where all right cell a of the i was a ritual a hope or in if fit this an a alt a waiting yeah i mean i was still the little to big even know i did shape a little off of the circuit boards of the make it fit but they did get a the fate at a positive uh the i have a i and a a and so i you might say why it the puzzle ten why this puzzle ten because if i took the car is can a wait from my signed it would scrape saul all the the make a a malice and down the or at t. and not so much apart so uh steed just some all cock but an read their are is uh there's there's these lightly more user friendly version a all right so what i'd done here or is i actually took at sixty for pay and development device of did i i e. in that i no but i and one way in around or so i and then l. c. d. screen and uh laws of all of nice leave it on top of all of a little per of or that i if him and late or oh uh and uh uh on to that i i i to ad to to pay a where at she nine more battery or tate five all up our regulator and a pot to adjust the hmmm i. e. i. whiting dean on the l. c. d. a. was cell right that it's all we gonna look so a it down so their are you have out this slightly more use your friendly version and now it's ain't new what as a i if mm knew so of the it it's see oh all right you all right buy the weight interested battery life is to what do you thanks that's a lot of our on this i talking it bat wise of it back light in the l. c. d. a. but ah um to in now way a lot all all that's sim my lug in i checked cos they did one of wok a to the airport a below all this home mate star and um i i thought or i the faq the i beefed up at the park uh who the power can winds scum end to the battery is a a you is it be i know know i you know we'd thought it start ten minutes lake now speech d. in just this is a true or or up it show all i that are the are you i don't know in the our uh own uh what with a well in is of in like she he how yeah at i a bar well u. s. um more pictures are you know how the around the if you want to c. in that later uh one last the vice the i one and what about what we is in the u. right an the want their this is the buys that i'd i to have a a lip the issues i um with that this is the vice f. to d. on i does come out of who would their car do we know oh clone directly call the ink alone out of the bingo of a cake to sly what the all uh oh it's smut up like that as a and of course it for at is improbable a public tim in to a a bad and uh this is it is a then should league going to be a oh okay you as v. you're right wok or ice say eventually because i i and some of the issues are rain in a catch me later if you one hear more about that a um i i didn't the white i get this is to wear one it it beep or to that i but uh mm i hmmm oh uh you ah uh_huh it is some future dry see as uh to using something like the sid in two you make an and a eight open ex s. freeze device i did ask their are demo's of that and it worse well all yeah and all the we some new me a to vices and that i i i anna was like a three we i you want it it still bring low and some if it's you a what or what uh uh uh with this is that thought a some who my it jack i be or some times if you and up in clark's in u. white one to have a sorta of buy the vice and the solution or that is it ad a new organisation and then i am in the process as of starting do a for a it it's cull it open source i bravado as excess so she a chef and then what is it it uh not it's about a a you've ink people ought all for ace to clue lacked hardware and software are specks fur a security n. forensic stuff come a like the are do we now a of the impose posts x. base is a way i a like to make a bit like a weather are do we all is to my crew controllers policy f. uh a hopes to be for uh in it was back to in a secure use cell it you can ask re more about that late i um air are some what's that i agree can i referenced and i'd ask or a question is but steeple should be a a have at in sell i guess un the dunn a set that a be around it if you you you have oh i should be but it would suggest i should the all would you will to be do a you have were i i i would certainly be one joule do had are in will a is sort of i i i i do
