Yes, same here. I have an 80MB Quantum drive with date of 1992 and it does not like to spin up these days. I have a dirty trick I use, though. I thrust it clockwise, basically, in the direction that the platters would spin. Doing this enough, and giving it power over and over again will get it started. But this destroys the drive. It's like doing drugs, each time you need to do more and more to get it going. When I first started, I could get the drive spinning in just 1 minute or so, now it takes as long as 5-10 minutes of this activity.
But it's not completely dead yet!
Dirt cheap, if you can find them. Prices are currently around $1 per gigabyte.
This is certainly a good tip, which applies to most all magnetic media as well. The better tip is to not store them in a cold environment. For this reason, I store all of my Apple equipment in my own bedroom where I sleep at night, for I know it shall be always warm there!
(this tip is not so convenient if you have a small room!)
