I know my system has a rootkit installed on it and I am trying to get rid of it. I tried to use knoppix to run chkrootkit, but when I try to mount hda2 it says
Mount:
I could not determine the filesystem type, and none was specified.

When I run
Code:

mount -t ext2 /dev/hda2 /mnt/hda2


it says:
wrong fs type, bad option, bad superblock on /dev/hda2, missing codepage or other error

Any ideas on how to get it to mount so I can scan it? It will mount the boot partition of the hard drive /dev/hda1
