Believe it or not, this does sometimes work on drives with hardware faults. If you're going to try this, make sure that you completely seal the drive ie. inside an anti static bag, inside a zip lock bag, inside a freezer bag inside another zip lock bag.
Sounds over the top, but you DO NOT want moisture in there at all!
Before you get to that extreme though, as johnhoh suggested, try the drive connected to an 80 pin ide cable (not 40 pin CD/DVD drive cable) and molex power connector.
If that doesn't work, try it in another external hard drive case (IDE to USB)
Then try it with a different IDE to USB adaptor. Ask any tech friends if they have an IDE drive caddy in their computer and if they'd be willing to help.
2 things cause harddrives to fail: circuitry and moving parts
and this is where it gets a little tricky...
The next thing I would look into is trying to find another hard drive that is the same brand, same model, same revision, and as close to the same batch date as the drive you have. If you do manage to find one, it's not that hard to swap the circuit boards over with a basic selection of small torx drivers.
Failing that, you really need to ask yourself how much that information is worth to you. Data Recovery experts can rebuild the insides of your drive, but they generally charge like a wounded bull, something like AUD$1200+ over here. Thats because it must be done in a dust free lab environment.
This last option is usually where I'd try the freezer trick
