Bigger problem My situtation is a little more complicated: When I plug the usb it gets a drive letter so, as I cannt erase information from the usb (it appears "it is not allowed because the drive is write protected"), I noticed the drive has many information which wasn't music, so I assumed it was a virus, the computers where usb is connected were protected with norton and avira and no one found nothing, so I used the autorun virusn remover which found somehintg and it appears it was cleaned. Although I couldn't erase information, and when I tried format a similar adviced related to write protected status appears). I tried to chenge privileges for access but they were blocked, I tried to access by the hard disks manager of windows and the only thing a could do was delete the drive letter, it wasnt possible to format. At the end I use ubuntu to access and although I finally erase all the information, when I connected it to windows all the files were there again, so I am writting here, I also tried to upgrade the firmware but it isnt detected by the sw. Also I tried with Paragon partition manager, in windows safe mode, but all it says is it is not possible.
