My Barracuda IV is suspended by elastic rope. When I first installed it, it was (accidentally) gently touching/resting against the front wall of the case. The noise was unbelievable - you could hear it in the room next door!
Guess I got just the right pressure against the case for maximum noise!
Thank you for your suggestion. I guess in this computer conference, the people don't know about medical doctors, nor car mechanics.
Both the trouble-shooters above use a stethascope to listen to the noise. If you work in PC SUPPORT, you can't just buy another replacement HDD after another. You need to find out how & why the fault developed.
For the computer novices who replied above, I suggest that they look at:

Hardware Tips: Don't Get Caught With Your Disk Down
"Learn how to tell if a hard disk is about to fail; make sense of dot-pitch numbers; change monitor settings quickly; try out a used PC before you buy.

Keep your ears tuned for any unusual noises coming from your hard disk: Strange sounds often mean big trouble; for examples, download .wav files of some common hard-drive-in-distress sounds. (Thanks to John Christopher of data recovery service DriveSavers.com for providing these files.)
A high-pitched whining sound (bearings.wav) could mean your hard drive's bearings are going bad. Relatively speaking, this is good news; you may actually be able to rescue your soon-to-be-stranded data. If your operating system loads and you're able to move files off the hard disk, do so immediately.
If you hear sustained clicking noises, you probably won't be able to access the hard disk at all, and your operating system most likely won't load. A pause-click, pause-click sound (cycleclick.wav) indicates that your drive's read/write heads are trying to orient themselves. The drive has probably sustained some damage, and you've likely lost some data. Continuous, rapid-fire clicking (excess.wav) is an ominous sound for any drive.
In either case, your chances of recovering your data manually are slim. Don't keep turning your system on and off in hopes that your hard drive will finally catch, or start up, one last time; it won't.
Any grinding or scraping sound (grind.wav) is another sign of serious trouble. Your hard drive's read/write heads are in contact with the disk's media surface--where the data is stored. Shut down your drive immediately; the longer it runs, the more data you may lose.
