Now, don't try this at home kids... but...
As a last ditch effort, I have had sucess in submerging (entirely) a "dead" Amiga drive into a bath of rubbing alcohol for an hour or so, then blowing out the unit with my air compressor (from a distance!) and finally letting the drive sit to completely evaporate for a day. Don't get me wrong, I wouldn't then turn around and sell that drive on eBay without noting that it had that done to it, but it *has* revived drives that were siezed or had spinning problems due to dust and oil buildups on moving parts (especially if the drive is in an environment with a smoker).
You could also just take it apart and clean it up with some q-tips and alcohol (that's what vcr cleaner is) but the soaking method is much more "mad scientist" and far more rewarding emotionally. :-D
