Have you tried looking at your drive with good ol' fdisk at a root
command prompt? If your Kingston is like my Vebatim, the output should
look much like this:

# fdisk -l /dev/sdb

Disk /dev/sdb: 8086 MB, 8086618112 bytes
249 heads, 62 sectors/track, 1023 cylinders
Units = cylinders of 15438 * 512 = 7904256 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1   *           1        1023     7896506   83  Linux

The key part to look for is the "8086 MB". If your 8 GB thumb drive only
shows something like 3.7 GB under fdisk, it's borked up internally and
you're done.

Otherwise, use fdisk's letter commands ("m" for menu) to delete all old
and create one new max partition of type 83 and "w"rite the new
partition table back to the drive. Then use mke2fs to format that new
