Title: 16GB USB flash drive has just become 8GB
Post by: motorollin on August 12, 2008, 09:43:06 PM
I've got an El Cheapo USB flash drive which was partitioned as 16GB. When I plugged it in today it appeared as 8GB. I checked in a partition editor and there was no free space on the drive. I tried deleting and re-creating the partition but it only allowed me to create it at 8GB. Tried zero-filling to destroy the partition table, then re-created it, but it still only allowed me to create an 8GB partition.

The fact that the capacity changed to 50% what it was before makes me wonder whether there are two chips, one for each 8GB, and one of them has failed. Is that possible? Would the capacity really just be reduced to a smaller, valid partition?

Sounds reasonable,

I have two 16gig ocztechnology Rally2s and one 8gig Rally2... all three do a fine job and were not very expensive :-)

PS they look right sexy too...

You could be right, one of the chips could have failed.

Then again It could have been 8GB all along with some sort of wizardry fooling your computer into thinking that it has more capacity than it actually has.

I've heard of this kind of fraud, usually in cheap imports though.

Btw, have you tried asking for half your money back?  :python:

A customer enters a computer parts shop.

Moto: 'Ello, I wish to register a complaint.

Moto: 'Ello, Miss?

Owner: What do you mean "miss"?

Moto: I'm sorry, I have a cold. I wish to make a complaint!

Owner: We're closin' for lunch.

Moto: Never mind that, my lad. I wish to complain about this USB pen drive what I purchased not half an hour ago from this very boutique.

Owner: Oh yes, the, uh, the El Cheapo Blue...What's,uh...What's wrong with it?

Moto: I'll tell you what's wrong with it, my lad. 'S half dead, that's what's wrong with it!

Owner: No, no, 'e's uh,...its fragmented.

Moto: Look, matey, I know a half dead USB pen drive when I see one, and I'm looking at one right now.

Owner: No no it's not dead, it's, it's restin'! Remarkable drive, the El Cheapo Blue, idn'it, ay? Beautiful casing!

Moto: The casing don't enter into it. It's half dead.

Owner: Nononono, no, no! 's fragmented!

Moto: All right then, if it's fragmented', I'll defrag it! (shouting at the device) 'Ello, El Cheapo flash drive! I've got a lovely fresh format for you if you show...

(owner hits the drive)

Owner: There, it's fixed!

Moto: No, it isn't, that was you hitting the casing!

Owner: I never!!

Moto: Yes, you did!

Owner: I never, never did anything...

AFAIK these thingies are often FAT partitioned, aren't they? Maybe google FAT specifications, to see if such a thing is possible.

-edit- you're of course using some unixish file system since you're using a mac, so no FAT I guess...

Post by: motorollin on August 13, 2008, 03:33:45 PM
Actually it is FAT since it is used to transfer files to a Windows machine. I'll have a look around to see whether it is possible for a FAT partition to remain valid once half of its physical medium has vanished.

Moto: (puts USB pen drive into display model PC, yelling and hitting the casing repeatedly) 'ELLO 'PUTER!!!!! Testing! Testing! Testing! Testing! This is your new removalbe storage device!

(Takes USB pen drive out of the computer and thumps its connector end on the counter. Throws it up in the air and watches it plummet to the floor.)

Moto: Now that's what I call a dead device!

Owner: No, no.....No, 's stunned!

Moto: STUNNED?!?

Owner: Yeah! You stunned it, just as it was auto detectin'! El Cheapo Blues stun easily, major.

Moto: Um...now look...now look, mate, I've definitely 'ad enough of this. That USB pen drive is definitely deceased, and when I purchased it not 'alf an hour ago, you assured me that its total lack of activity was due to it bein' tired and shagged out following a prolonged disk test.

Owner: Well, it's...it's, ah...probably pining for some media.

Moto: PININ' for some MEDIA?!?!?!? What kind of talk is that?, look, why did it fall apart the moment I got it home?

Owner: The El Cheapo Blue dismantles for storage in bits! Remarkable drive, id'nit, squire? Lovely casing!

Moto: Look, I took the liberty of examining that drive when I got it home, and I discovered the only reason that it had the extra flash chip in first place was that it had been NAILED there.

(pause)

Owner: Well, o'course it was nailed there! If I hadn't nailed that chip down, it would have slid up to the casing, bent 'it apart and VOOM! Feeweeweewee!

Moto: "VOOM"?!? Mate, this drive wouldn't "voom" if you put four million volts through it! 'S bleedin' demised!

Owner: No no! 'S pining!

Moto: 'S not pinin'! 'S passed on! This pen drive is no more! It has ceased to be! 'S expired and gone to meet 'its maker! It's a stiff! Bereft of life, it rests in peices! If you hadn't nailed the chip to the PCB it'd be pushing up the daisies! 'Is electronic processes are now 'istory! 'S off the board! 'S kicked the bucket, 'S shuffled off it's mortal coil, run down the curtain and joined the bleedin' choir invisibile!! THIS IS AN EX-PEN DRIVE!!

I don't think FAT will remain valid after half the physical medium vanishes.

for how long did you use it for 16 gb ?

maybe someone stole your 16 and replaced it with a 8 gb one ?  :crazy:

People say that about socks, but we all know there's a wormhole network connecting sock draws across the world with each other as well as other people's washing machines...

When I first read that I thought it said "womble network" :lol: Well, as long as they make good use of the things that they find... That makes me wonder who could have created the wormhole network for the purposes of abducting people's socks. Obviously somebody with a penchant for woolly footwear..... ;-)

@ Moto

I hate to be the bearer of bad news mate but it does look like you got stung by one of the biggest scams going around concerning flash drives.

The same thing is also very prevalent for the cheap usb mp3 players from china as well ... you have been warned!

The worst part of it all is that you don't even realize you've been scammed until you have to format the flash drive. This wipes out their doctored FAT thus revealing the true size of the unit's storage capacity.

Heh, the first MP4 player I bought (From a supermarket) was supposed to be 2GB. Suffice to say it was only 1GB (And that was just by looking at the memory info page on the device). Took it back. The next one I got reverted to Spanish every time I turned it on after the so-called recommended firmware update. Took that one back too.

I must be on my 3rd or 4th now. Sigh. (Well, they are cheap £25 models, and I hardly use it anyway, so I can't really complain...)

The worst bit is they don't actually play MP4's. The converter software supplied with them that converts videos to the format that they do play doesn't even have the ability to convert MP4's.
Apart from that, no PSU was supplied for charging, so I had to charge the thing from the PC until I got a USB charger for it, and even then I had to buy a USB hub for the charger to "fool" it into thinking it was connected to a PC and to allow it to go into standby (Otherwise the screen would be lit all the time). Grrrr. The charger PSU I got for it blew up anyway not long after purchasing it and needed to be fixed (Output rectifier short in both directions). Sigh.

Just to revive this thread...

Last week I bought myself a new USB flash drive. I was primarily interested in getting something a bit more rugged than usual so I plumped for this (http://www.aria.co.uk/Products/Peripherals/Memory+Portable/USB+Pen+Drives/Pretec+8GB+USB+Bullet+%2B+Ultimate+Secure+Guard+?productId=37506) model, a drive touted as being water, fire, high impact and even bullet proof, not to mention high speed for a pen drive.

Been using it all week on my linux system(s) and I was was entirely satisfied. Until today. 5 minutes after plugging it into my brother's laptop (running 32-bit Vista) and it's toast. It can't be read, written or even formatted :griping:

So, it may be able to withstand all kinds of physical punishment but leave it to Windows to find some way of destroying it :-/

I'm hoping that when I get back, linux will be able to sort the disk out but I suspect I'll probably end up having to take it back.

Motorollin, I was stung too on one of those el cheapo thumbdrives. Same exact problem. Was once 16gb (but never really worked that way), then it magically turned 8gb. Figured, okay - I can still use that... but soon after she started puking up blood and I had to lay her to rest permanently. Good lesson to be learned here, eBay and el cheapie mass storage solutions from China are a terrible combination!  lol

Things like this is why I always buy from my local pc shop.  Or Novatech.

Never had a problem with either place.  The local shop is run by a friend of my sisters so I kinda know them.

Siouxsie's bought one or two pc related things from ebay and regretted it a month or so later.  I don't think she's logged onto ebay since ;)

Well, no luck with (g)parted, looks like the drive is actually broken. The size is reported correctly, but the entire space is unallocated. It refuses to let me create a new file system, from the looks of it, the drive reports itself as being write protected, despite having no write protect switch.

Brilliant. It'll be the weekend before I have a chance to return it to the shop I bought it from.
