Мастера, бля

Back in 2005 some hacker has figured out how to trick Windows into misreporting total capacity of a flash drive. I only found out about that recently; so when I saw a cheap 8 GB drive on Ebay, I decided to check this out.

These pictures were included in the listing:


I bought it for $7.50 (free shipping) from cckstore78, a Power Seller supposedly in Rochester, New Hampshire.

First off, the 4 kb of used space was occupied by a hidden Autorun.inf - probably a virus loader. Autorun is disabled on my PC, so that's OK. I re-formatted the drive and tested it with Bart's Stuff Test. Sure enough, the drive topped out at 4 GB. (Write speed was 3.2 MB/sec.) Some drives I've read about were sold as 2 GB but were 128 MB...

So how do they do it? And what can I do beside leaving negative feedback? (I actually left neutral, because the price was OK for 4 GB.)

No, it's a hack. My PC showed the same information. They can trick the file system somehow.

HOW???? do they do it?
and how do you fight this? Does formatting help?
how did you find out that it's smaller if your PC shows the same info?
Does formatting the drive help?

I don't know how this is done, but would like to find out. Formatting does NOT restore the actual size. I tested it with Bart's Stuff Test, and it was able to write 4 GB of data before running out of room. Actual usable size may actually be less; yesterday I copied 4 GB worth of test files onto it, and after I copied them back to the HD, some were corrupted. It's an interesting project :-)

Pls, let us know how it's going.
May be another 8GB are corrupted?
