I've got a buddies CPU here that I need to transfer files from one partition to the other.

Knoppix seemed to be the best way, simply because it has a GUI to makes things more simple. However, it seems Knoppix is not detecting his SATA controller, because when I cat /proc/partitions, it only lists cloop1.

Is there someone here familiar enough with Knoppix to guide me?

Here's his SATA controller:

Code:
0000:00:0f.0 RAID bus controller: VIA Technologies, Inc. VIA VT6420 SATA RAID Controller (rev 80)
