After reading an article in PC Mag about Knoppix I thought I'd take the plunge. I'm running the latest CD Live version of Knoppix. I am a total linux novice, but am reasoably experienced with PC's. I'd like to use qtparted v 0.4.4 to partitition my winXP ntfs primary partition, and am assuming that qtparted can do this. I get the root and launch qtparted:
su
qtparted&
It picks up my hard disk and gives me my primary partition info which all looks fine. My Primary partition is about 80G, I want to resize it to say 50. Change the size withg the slider and OK, no repsonse for about 30 seconds and I get a message saying "The NTFS volume has at least one bad sector". I am then not able to commit the changes.

I've run Gibson's SPinRite and my hard disk is clean. Am I missing something obvious?
