Hard Drive Failure?

Generally a clicking sound coming from your hard drive is a Bad Omen. It could be a harbinger of horrific hardware happenings, so my immediate advice is "BACKUP YOUR HARD DRIVE!" as soon as possible. If the drive fails, you're out of luck. In fact, even if you don't suspect a problem with your hard drive, it's wise to make regular backups so you can survive a hard drive failure with only minimal inconvenience. See my article Backing Up Your Files to learn about backup strategies, hardware and software.

Scan Your Drive

On Windows XP, you can check your hard drive for errors by running the CHKDSK utility. Restart your computer and hold down the Ctrl key while it's booting up. When you see the option to start your system in Safe Mode, select it and continue. Click the Start button, then click Run, then type CHKDSK C: /F /R then press Enter. The /R option tells CHKDSK to scan for bad disk sectors, and the /F option means to fix any errors found. (On a Windows 98 system, use the SCANDISK command instead of CHKDSK.)

If CHKDSK offers to "convert lost chains to files", recover lost data, or fix something else, you should accept. (If CHKDSK tries to sell you a cheap Rolex, politely decline the offer.) After CHKDSK finishes, restart your computer normally and see if the dreaded click of doom returns. If so, the drive is most likely damaged, and should be replaced as soon as possible. If you decide to purchase a new computer, see Copying Old Hard Drive to New PC for help with transferring your files.

Are You On The Level?

But before you trash your troublesome drive, you should try one more thing... Some hard drives are very sensitive to non-level surfaces, and will not function properly if they're sitting on a slant. Shut down your computer, make sure your system unit is on a flat surface (use a level to make sure), and then restart. I was all set to give up on an older computer that was doing the click/whir routine, but I noticed it wasn't sitting on a level surface. As soon as I fixed that, the problem was gone!

That clicking sound MAY signal impending hard drive failure, but keep in mind you don't always get such a warning. So play it safe... back up your files on a regular basis.
