I had a laptop drive that would not spin-up too. I took it apart and freed the stuck head. Put it back together and it worked. I was able to get my data off the drive and I imagine I could have continued to use it however I defiantly did not trust it anymore.

I know everyone is shrieking in horror because I did not wear a space suit in a clean room but it worked and did not cost me $1200.

Be warned this might not work and you will likely loose your warranty.
