This could've been a comment on Kromey's question, but I wanted to emphasize the advantages of: disassemble the drive.
First, it's a bit of fun, getting to take a precision device apart and not having to worry about whether it works when it goes back together. It's a good excuse for the company to buy a good set of Torx screwdrivers which are often handy for other things.
Second, when you take the drive apart, you can scavenge the voice-coil magnet(s) used in the head positioning mechanism. They're powerful rare-earth magnets, incredibly useful, even if all you want is a super-strong fridge magnet. Once you have a bunch of voice coil magnets, you can use them to wipe the platters.
It's a win-win-win, especially when you include the possibility of wiping your friends' credit cards!
