WARNING: This process will delete any information that is currently stored on the USB key.It might not work properly on every USB Flash Drive (as it was created by HP for HP drives). Proceed at your own risk!
Few easy steps:
Restoring your USB key to it’s original state using Linux:
A. First we need to delete the old partitions that remain on the USB key.
- Open a terminal and type sudo su
- Type fdisk -l and note your USB drive letter.
- Type fdisk /dev/sdx (replacing x with your drive letter)
- Type d to proceed to delete a partition
- Type 1 to select the 1st partition and press enter
- Type d to proceed to delete another partition (fdisk should automatically select the second partition)
B. Next we need to create the new partition.
- Type n to make a new partition
- Type p to make this partition primary and press enter
- Type 1 to make this the first partition and then press enter
- Press enter to accept the default first cylinder
- Press enter again to accept the default last cylinder
- Type w to write the new partition information to the USB key
- Type umount /dev/sdx (replacing x with your drive letter)
C. The last step is to create the fat filesystem.
- Type mkfs.vfat -F 32 /dev/sdx1 (replacing x with your USB key drive letter)
That’s it, you should now have a restored USB key with a single fat 32 partition that can be read from any computer.
