Did you run the basic utilities? ScanDisk included with Windows and such?
Run that, and also try HD Tune (Google it). Download it, install it, select your drive, and check the health tab. If it says it is fine, then go and run an error scan. If that doesn't come up with anything, you should probably reformat and see if it works again. Failing all of that, try calling the manufacturer. It should be under warranty.
