In all honesty, I've never had a situation where I've had to copy all the data from a drive onto another, but I'd (and again, I've not done it, so anyone who knows of a problem with this solution, feel free to reveal it) boot in DOS mode, then type (assuming that the first drive is C and the second D) "copy C:\ D:\" minus the quotations. I'd wait for a second opinion on this before doing anything, because I've not done much of anything on an XP system, and I'm not entirely sure of that being a viable solution to begin with. Sorry I can't offer a definite answer, but it's somewhere to start looking.
