I'm having a strange problem with my hard drive. It seems to make a single clicking noise, but only after certain actions. The click only happens when I access certain websites, or if I run a maintenence program (it happens without fail everytime I run Spybot, Avast, and XP's built-in defragmenter). All the research I've done seems to suggest that my hdd could be on the brink of failure, but I'm not so sure this could be the case with mine. The click sounds exactly like the sound a 56k modem makes right before it dials out. No, I don't have a modem, but my mobo does have an onboard modem device. Occasionally, it isn't even a click, but more like a chirp, which I can only describe as similar to the sound your PC speaker makes when you access sticky keys in windows XP via hotkey (try it.. press shift 5 times in rapid succession). The hdd is a 200GB Seagate 7200.8. I've run chkdsk from DOS, window's scandisk, and the utilities that came with the hdd, but none of these programs report an error. Any ideas.. or should I start saving up for a replacement? Also, is there a better hdd diagnostic software that I can and should be use?
