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?
