Why does one of my hard drives make a loud clicking sound every now and then?

Although my computer running XP pro appears to be ok, every so often one of my 3 hard disks makes a louder than usual clicking sound.

What should I do?

Hi TonyCabone,

It's possible that your hard drive is bad or going bad. I would try running some diagnostic tests.

Can you recommend any free software available?
Get the UBCD http://www.ultimatebootcd.com/

Download links are the icons at the top of the page above Overview.  Browse the page and see what utils are there for you.  Check the memory and hard disk utils especially.

Make the CD and boot from it.  

Then test the hard disk with the correct manufacturer's util for your hard disk.  Do the long test.  That will most likely diagnose any disk problem.

The sound may be normal.  It just may be a characteristic of that disk.

Also examine HDTune http://www.hdtune.com/ (the free version).  This can give an indication of the state of your drive.  Indication only.
as said - that probably is an indication of a failing drive.
check if SMART is enabled on that drive -  it will warn you of it's status at boot
and testing the drive is a good start to know it's status - if it comes back ok, run a chkdsk on it
The UBCD is a good one to try first as dbrunton mentioned. However your still looking for a good hard drive diagnostic tool, it's not free but it's really good though, it's called SpinRite. Here's the link: http://www.grc.com/intro.htm
