I am running 5.1 from a bootable CD and am completely new to this. I have spent hours researching this website and have tried various suggestions. I am now desperate and decided to post. I greatly appreciate all help.

I can no longer boot up windows XP Pro. I am getting the common disk read error. After booting up Knoppix, I have attempted to mount the hda1 partition unsuccessfully. A gpart -v /dev/hda1 provides the following information:

From reading other posts I saw the inconsistencies of the partition sectors not ending in 63. I executed sudo cfdisk /dev/hda. The results displayed one partition (hda1) with the following C,H,S - 9729,255,63. I honestly don't know where to go from here. My ultimate goal is to recover some files from my hard drive. Once again, thanks for your time and help.
