You may be able to save your USB drive if it stops functioning. Recently I had a USB drive I use to push firmware on DVRs that did not show its full capacity. The USB drive could not be formatted and the Disk Management Utility was of no use.
Warning – IF YOU SELECT THE WRONG PARTITION OR DRIVE LETTER, YOU MAY DELETE DATA. REMEMBER, YOU WILL ERASE WHAT IS ON THE USB DRIVE, BUT IT SHOULD BECOME FUNCTIONAL.
Open a command prompt as an Administrator and type what is in the bold, CHANGING the partition information and drive letter as necessary.
Follow the steps below to fully ERASE and reset the drive –
