Encrypted flash drive using AES-twofish-serpent, formatted back to default, now write protected.

Greetings,

I recently encrypted a Sandisk 32gb flash drive using truecrypt, with the algorithms stated above. After successfully encrypting the device I formatted it back to factory default in Windows 7, as I have no need for the drive to be encrypted. I've encrypted files and containers before but had never encrypted an entire storage device and was just curious on the process. Anyway, I had no problem formatting back to default. Recently, I copied about 12gb of video files (True Detective season 1 in MKV format to be exact) to bring to my brothers. His computer read the files fine, watched the show, had a great time.

Now the problem. I tried to copy some stuff to the drive yesterday and it's saying its write protected. I can't format the drive, I can't delete the files, I can't add to the drive. I get the write protected error on each. I've tried multiple computers and OS's(XP,vista,7,etc). I've tried everything. There is no switch on the drive, I've cleared all attributes several times in DiskPart, which has stated it's not in read only right from the start. Windows has no problem detecting the drive, it behaves like normal, I just can't do anything to it. Did my curiosity perma-screw this thing? Should I have unencrypted the drive before I formatted it? I feel like that is what screwed it up. It's just very odd that it worked fine after I formatted, and seemed to write protect itself after I had written new files to the drive.

I'm out of ideas. Anyone have any? Thanks.
