    usb flash drive disk write

    my usb is apparently disk write protected. there is no physical switch on the usb. i can't understand it as it was working perfectly one day & the next it was write protected, it maybe to do with the fact that i formatted with 'wii backup manager' allowing me to put downloaded wii games onto the usb & play it on the wii, but i can't remember if i done this or not.
    i googled the question and someone said to run cmd, diskpart, list disk, select disk X, attribute disk clear readonly, clean. it goes on for a few more steps but at this point i get the error message "DiskPart has encountered an error: The request could not be performed because of an I/O Device error.
    See the system event log for more information"

    what can i do. the usb is only around a year old so shouldnt be damaged already

    I had that happen to me once with a portable HDD after I tried using it with an Xbox 360. Got that same error. Only thing I can figure is something happened and it messed up the controller on the drive itself somehow.
