Best solution is to remove the top cover.
there was a whole argument on one of the Mac Facebook groups about this a couple of months ago. Some guy had a dead Quantum drive, popped it open, there was a plastic piece that was locking the head, if you wiggle it the drive works for a couple of days, and then stops again, and he was asking if it was safe to either remove the plastic piece, or make it so it stays out of the way, and posted a pic of the drive cover popped up, and people freaked out. "This drive will never work again now that it's been exposed!". "You should have sent it off for data recovery", like, people were thinking this was his main hard drive on his main computer or something? whole thread was a mess
But yeah, I've gotten older drives to work again, lots of times seems like either the platters or head gets stuck. But I have ones that I've popped open years ago, got working, and they still work. Do it in a fairly clean room(not like, a woodworking shop or anything), don't touch the platters directly, close the drive up as soon as you can, and obviously don't keep anything important on their without a backup.
