I haven't replaced mine, but I've taken out my HDD and put it back in, so pretty much the same thing. The little blue screw on my old school 80gb model was a pain to remove, literally took me hours and I did the filing step too, after I ripped it to shreds. Very annoying.
No advice though. That happened 6 months ago and I've been trying to remove all memories from that ordeal from my head.
