I have an 8GB Ridata USB flash drive. My friend brought it to me yesterday and it appears that I fried it but it would not hurt to ask around. Anyway, what happened was that the flash drive was acting 'weird' as it did not 'copy back' any folder that I would put on it.
I did a quick check disk and it reported errors and I opened the drive and found a bunch of hidden word files with 'exe' extension and an 'autorun.info' (yeaaa i know, VIRUSS). Trying to delete the files manually only reported a 'files are write protected error'.
Sooo, I embarked on the tedious process of cleaning the flash drive which apparently turned bad .
What I tried was:
1- Booted in safe mode and tried to delete the files manually but it did not work ( there was even no 'delete' option for the files on the flash drive in safe mode!!)
2- Formatting the drive also did not work as the files reappeared when using check desk and the problem persisted.
3- tried the old 'storagedevicepolicies' trick in registry but it still reported 'write protected files'.
4- Booted through win7 installation disk, clicked 'shift+F10' to bring the console and tried using 'diskpart' to clean the flash drive but all I met was the obnoxious error of 'the media is write protected' .
5-Tried 'low level' hard disk formatting tool but it did not work either.
6- Under the same cmd through win7 installtion disk, i tried to us an mbrfix tool but it could not do anything to the drive and reported it as write-protected as well.
I am totally sad and frustrated at how this turned out as I didn't expect that a silly virus would actually lead me to lose the pen drive.
Does anyone have a trick up their sleeves to help me with this or should I accept my destiny of buying a new pen drive for my poor soon-to-know friend?
