*note:I am a knoppix newbie(linux too)

Windows has failed me and my win xp cd screwed my windows over.

I want to back up the files the setup is gonna format so im using knoppix but i cant move any of the files anywhere except my desktop.(which i dont know which drive its one).

Can someone tell me what to do that lets me write anything onto any hard drive using knoppix, step by step preferably.
