Also I ran fdisk -l and this is what I got /dev/sda1 /dev/sda2 /dev/sda3 /dev/sdb1 /dev/sdb2 /dev/sdb3 disk /dev/md0: 106meg /dev/md0 doesn't contain a valid partion table disk /dev/md2: 15.9gig /dev/md2 doesn't contain a valid partion table disk /dev/md1: 2097meg /dev/md1 doesn't contain a valid partion table Does that help at all?
