If you have a drive you don't mind messing up, try running something
like "mke2fs /dev/sde" changing /dev/sde to match the drive you are
using.
# mke2fs /dev/sde
mke2fs 1.39 (29-May-2006)
/dev/sde is entire device, not just one partition!

As you can see, the drive does not have a valid partition table, but
it does have an ext2 file system on the entire drive. It will mount
just fine. The drive I used was an old laptop IDE hard drive on a
USB to IDE converter, but it will also work on an internal drive on
a PATA, SATA, or SCSI controller. It should work on any drive that
has a /dev device entry. What is even more interesting is that it
will also get auto-mounted on my FC6 system.
