Hi, is it an internal drive, or external? USB or Firewire?
If you boot up holding alt or option key, what choices are shown to boot from? And if you can select that drive there, does it work any better?
Normally the Spinning gear means it's trying to Repair the Disk, & if it just goes on forever it means it can't for some reason... usually.
