S.M.A.R.T.

Hay guyz,
My hard drive reports 240 S.M.A.R.T. errors. Mostly read/write. Time to replace?

Good, I'll do that.
Any hints how I could retrieve my data, somehow copying doesn't really want to work, i.e. completely crashes my system (booting from CD).
There is not a lot I need to get from there, as most of it is already redundant. Could my IDE-controller mess with me, so another PC would be more successful in retrieving my wanted data?
