Spotting a Fake USB Drive from eBay
So I bought a “64GB USB FLASH DRIVE USB 2.0 PEN STICK MEMORY 64GB” from eBay for $23 shipped from China a few weeks ago, and it just came today. I was skeptical, because I’ve had experience with getting incorrectly sized flash memory from those Chinese eBay scammers.
I found this guide, which says
It’s one thing to be sold the wrong size drive, but these “hacked” drives which appear on your computer to be the right size, actually corrupt your valuable data to make it look like it fits on a much smaller capacity memory chip.
I followed their guide, and sure enough, my 64GB drive is closer to 20GB, or 21,850,329,088 bytes. The first file after this amount looks like this:

So I filed a claim on eBay, hoping to get this refunded. Turns out the seller’s account “no longer exists”. Meh. Moral of the story (which I should have already known): if it looks to good to be true, it probably is.
Edit: Ebay gave me a full refund. Hoorah.
