Restoring your USB key to it's original state using Linux:

Show key headers only | View raw

I thought this would be helpful information for someone having trouble
with a USB stick. I restored one that I was going to throw away, using
these instructions.

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/sdx1 (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.
