I agree with Gecko on the hard drive Diagnosis. If you know the manufacuture of the drive and have access to another computer, then go to their web site and download a diagnostic floppy disk and run that.
You can boot into the bios and see the type of drive installed WD is Western Digital, which I believe is WD.com FJ is fujitsu.
Sometimes the floppy diagnose disk can repair the glitch and stop the clicking. If not, time is limitied especially if you want to recover any data. If thats the case, take it to a tech, he still might have time to recover some or all of the data. Just don't leave it on clicking away.
