How come my 16GB USB thumb drive is reporting at 64GB?

by on December 5, 2012

Q: Hello, I am in need of serious USB help. I am running Windows 7, and my friend was copying a game (6GB) onto my 16GB USB. Since the copy was not finished when we had to get off the bus, he left it in his computer to continue copying. I saw him again a few hours later, he said the copy had finished and handed me my USB. When I plugged it in, it says that the device needed to be formatted before use. Confused, I clicked the x on the dialog box, and tried to access my USB through ‘My Computer’. Same thing, wouldn’t let me open it. I tried the format, and this is where I am worried. Under the ‘Capacity’ tab, where it should say 14.9GB, it says 64MB. The rest is fine, and when I clicked Format, it says ‘Windows could not format device E’.

ADDITIONAL INFO:
This USB is brand new, bought two days ago. It is a 16GB SanDisk CruzerBlade. It is not the computer, as my 2GB USB works just fine. I need urgent help, thanks!
ALSO, I think the problem is that he just ripped the USB out without clicking ‘Safely Remove Hardware’. I hope you can help me.

    You’re probably right.

    Check out this article for details on how to correctly wipe your USB stick so it shows the correct size again: http://helpdeskgeek.com/help-desk/format-usb-flash-drives-showing-the-wrong-capacity-the-easy-way/

    After that get your friend to copy your data again, and make sure he removes the USB stick correctly this time 🙂
