    usb flash drive - "Disk is write protected"


    My Sandisk 32GB USB Flash Drive doesn't allow deleting of files nor Formatting. The message reads "Disk is write protected". Since all it holds now is 'old stuff' its useless. Can we restore so it can be used again?

    try the following if you haven't and hope it helps
    1. Insert the USB Flash Drive
    2. Don't open or format it directly
    3. Right click on my computer and go to manage
    4. In computer management window click on disk management option
    5. Right click on the USB Flash Drive
    6. Select format

    flash memory degrades because of the limited number of write cycles, which means the more you delete and write new information, the more quickly device will become useless...i.e. 'read only'

    could be you've used it up...
