I cannot delete or do anything with this USB. Here is the information error in Gparted: http://i.imgur.com/bwdxpXe.png

First it was all good, I created new MS-DOS partition table, formatted it, but now it's not working. I cannot format it in windows either, it says it's write protected.

When I try to delete it using Gparted it says: Input/output error during write on /dev/sdb

Thanks for any help!
