Don't fall for the Flash Drive Scam!

Don\
Hey Guys- I recently became aware of a major scam on eBay. Hackers in China are selling flash drives with less memory than they advertise. Users like PikesPeakTraders sell thousands of 'hacked' flash drives from China. The problem is that the hackers change a log file that makes the flash drive think it has more memory than it does. When you receive the drive, if you right click and go to properties it will display a larger amount of memory than it really has- so when you put data on it that exceeds it's actual memory, old data will be deleted.

This problem is nearly impossibly for the average Joe to detect because the flash drive looks and works normally- until it's memory is filled.

Here's how to protect yourself from this scam:

Step 1How To Buy

How To Buy
So you want to get a nice, high capacity flash drive for a friend for the holidays. Here are a few cardinal rules to follow to avoid getting scammed:
(if you've already bought an unbranded flash drive online, skip to the next step)

1) Buy a brand name flash drive
-Most brands are reliable in terms of storage. Most unbranded drives aren't

2) Know your product
-I was naive enough to think that many companies (including unbranded ones) are producing 16GB flash drives- I could be wrong, but I believe the only company selling one of that size is Corsair. This goes for any size...

3) Look on the packaging
-If the buyer shows a picture of the packaging, see whether the storage is printed directly onto the packaging, or if there's a sticker on it that has it. If it's printed on, it's more likely not to be a scam as that means the company probably hasn't tampered with it

4) AVOID BUYING FROM EBAY!
-Ebay has been seemingly overrun by scam artists selling falsely listed items- avoid buying anything that's not a well-known brand name from Ebay at all costs!

I think its better to put it in the "system32" directory (usually C:\WINDOWS\system32) because if you do, when you type only the name of the file, it will run, so you don't need to type C:\ or anything.

Man it really sux that this wont work with windows 7...i ave an ATP Tough Drive that is really a 4 gb drive and properties is only showing that it has 1.89 gb available...it should really be 3.89 gb available...
Jan 11, 2012. 8:49 AMsokamiwohali says:
HAHA...well nvmd...i got the program to work, but it shows that it its correct...but i know it is a 4 gb flash drive...

Wow Thank you so much. Currently, I am thinking about buy a 64G usb drive from ebay. I will reconsider about it before buying it.
Oct 18, 2011. 2:05 PMashannon1 says:
you might want to invest in a 1 terabyte external harddrive from an electronics store, or Walmart, get sea-gate, or something simaler. somthing with a lifetime warranty. much more space than 64 gigs(936 gigs more), and it will be pretty much guaranteed to have that said amount, of space, if not, return it and get a different brand.

In this case it is more like the rule of thumb...drives...
Sep 27, 2008. 4:41 AMcollard41 says:
32gb are fakes, so 64 is 100% fake
Jul 2, 2009. 1:08 PMNyxius says:
I own a 32 GB flash drive from micro center...it is completely legit and I'm thinking about buying their 64 GB version. Large size flash drives have been around for a little while now, but were just to expensive.
Oct 4, 2008. 7:18 AMDerin says:
transcend makes 32 gig flash memory

Toshiba Have a 128Gb hard drive, solid state, but this isnt a pen drive. it is for laptops like the macbook air.

I got Frauded by pikepeaktraders too. My 16GB drive only holds 1.9GB before it starts corrupting data. This is dangerous because you think your saving data but it is really corrupt. Keep in mind the drive are hacked so acts like it is 16GB so you won't know until it is tested. (Just wanted to reiterate)The testdrive.exe isn't downloading properly, here is on ebay is a test bat file and instructions http://reviews.ebay.com/HOW-TO-TEST-FOR-FAKE-USB-DRIVE_W0QQugidZ10000000003664934

I know it has been more than 3 years since you posted the link, but thank you very much Presman. It helped me on checking my flash drive, I thought it was fake, but it is real! I guess eBay has a few honest sellers.

just change file from XXXXXXXXXXXXXX.tmp to testdrive.exe it is like that because you usually cant put .bat, .exe, and others on the internet. ive downloaded from instructables before, and its always like that.
Jan 23, 2011. 7:00 PMPuzzledd says:
VERY useful 'ible, thank you!!
Dec 4, 2010. 8:50 PMaccount3r2 says:
on my cpu it takes so long, but i think its worth it.
Jan 16, 2009. 6:33 PMmaxpower49 says:
when i go to downloag the test drive it gives me some wierd file
Apr 13, 2009. 5:23 AMaka_bigred says:
I had the same problem with the download. You can just rename it to "testdrive.ede" and it works. Not sure what the problem is, but worked perfectly for me.
Dec 4, 2010. 8:19 PMaccount3r2 says:
its because you arnt allowed to post bat exe and some other types of files on teh interwebz

Sandisk makes them too. I use one to keep a backup disk image of my netbook on.

Seagate sell 16GB thumb drives I think

http://www.frys.com/product/6197469?site=sr:SEARCH:MAIN_RSLT_PG legit and hold close to the reported capacity
Jun 11, 2010. 10:03 AMsgt_rock says:
Apparently, they've been able to do this with micro SD devices, too. I've bought a few that I thought had failed because they turned out to be inky dinky compared to what I believed them to be.

If you go through paypal (most common buyer-seller online service) they have a dispute too, although i have never run into this problem with chinese manufactures, they always seem to help alot... expect there idea of "Air mail" is a 1 month delivery time...

Micro center sells 32 GB drives as well as 16 GB drives...custom branded...not sure about the supplier, but they are legit.
Jun 3, 2009. 5:54 AMLedviper says:
how common is a response like this? "Dear Buyer, I don't know what is happening to the item, I deeply apologize for the technical mistake, please allow me to resend you the new one, or, I can issue you full refund, kindly accept my apology and let me know which one solution would you prefer? Best regards,"
Jun 28, 2009. 4:03 AMmunchman says:
I'd say pretty common. They are trying to guilt you into thinking it was a nhonest mistake. Don't fall for it.
Feb 3, 2009. 4:26 PMIzokay says:
Pretty much all drives including MP3 players only hold about 15/16 GB that they advertise. Examples: 160 GB - 150 GB 320 GB - 300 GB 8 GB - 7.5 GB
May 7, 2009. 10:35 AMneumanngregor says:
It is a space calculation difference, hardware producer use 1 megabyte = 1000 and software actaly use 1 megabyte = 1024, thats why your 500 gigabyte harddrive hase only 464 gigabyte after is formated, same with all memory storage (harddisk, usb, mp3/mp4 players, ...)
Mar 19, 2009. 12:13 AMjchar77 says:
Yeah, they would. Its just like hard drives. They round the number of gigs to the nearest 10gb number for sales purposes. I mean what would sound better: Sale! 187.3GB hard drive for sale! OR Sale! 190GB hard drive for sale! That would attract more customers. And also you lost a bit of space when you format the drive. Hope I helped...
Apr 26, 2009. 10:26 PMliny says:
Actually, the Drives DO store up to 160 GB for example. Because this is counted as the TOTAL amount of memory. The only problem is that the FAT and the OS (in case of Hard Disks) occupy space and the space left is normally 15/16.
May 25, 2009. 4:51 AMarikyeo says:
but there is another thing: normally, they will reserve some space, normally 0.001-1% of space for the "boot sector"(or rather, in some cases, it stores drivers, system files, and such) and are not usually accessible.
Feb 19, 2009. 12:59 PMlemonie says:
Isn't it the case that they claim total drive capacity, rather than usable storage space on the formatted drive? The file system has to take up some of the drive. L

Micro Center (A store,you know with the doors and the employees)carries 32GB flash drive.
Mar 19, 2009. 12:09 AMjchar77 says:
Did you make the code for that program????? Thats amazing! If you did, then could you send me the source code? I can help improve it and add features! If you didn't make it, then plz tell me where you got it from. If you did make the program, then please send the source code to lordoftheFARTS@hotmail.com Thank you!

Thanks for writing this Instractable, I bought 2 SanDisk Cruzer Micros about 2 weeks ago, just read this about 3 days ago. I was pretty freaked out until I tested them and they were ok!
Feb 13, 2009. 12:17 PMThe Real Dave says:
Sandisk are a good company, so your in pretty safe hands. Their also some of the best flash drives around :D
