Getting knoppix to recognize my RAID-0 array

Hi all. I got the problem that somehow my mom's Windows XP installation got corrupted on a RAID-0 array. I cannot get it to work in XP's recovery console, so I thought I'd give Knoppix a try to make some backups (which, of course, haven't been made in a while). However, Knoppix 4.0.2 doesn't recognize the disks to be a RAID array. It only shows two seperate devices: hde and hdg4.

The two disks are installed on an onboard promise RAID controller (PDC20276). Is there a way to get the disks recognized to be a RAID array instead of two seperate disks?

Thanks
