The other day I started hearing a soft cooing sound (like the sound doves make) coming from my Computer. I opened up the case and can't pinpoint the sound nor can I feel and wobbling. I think it might be a hard drive so I ran a check with HDD health. You can see screen shots of what HDD Health reported here: http://www.members.cox.net/rtadams89/5.bmp http://www.members.cox.net/rtadams89/2.bmp Please tell me what you think. PS I have 2 hard drives as you might have noticed. The WD one is only a year old while the Quantum is maybe 4.

Why don't you unplug the power cable off of one? Start it up. It doesn't need to boot into the Operating system to make the sound. If the sound is still there after you unplugged the power from that HD, plug it back in and unplug the other one and start it up. Any noise changes? If not, look elsewhere, like the cpu fan or the Power Supply fan.

I was going to reccomend that you download a copy of HDD Health, but I see you are already using it. From the information displayed, you hard disk seem in good health. I would start worrying if the Seek Error Rate starts getting out of hand. As rainckeck suggests, the noise is probably coming from one of the fans. For future reference, if you want to make a graphic image avaialble on-line for others to look at, save it as a JPEG image. Its a lot smaller with minimal loss of quality. BMP images tend to be a bit on the large size. If I had been on a dial-up connection I would not have botherd downloading the images. Stuart

does it make a rattling sound?.. because mine makes a rattle sound

Normally I do use jpegs but i was in a hurry. It is sort of random so I have to leave it running for a while. I have linux on one harddrive and windows on the other so i'll paly around with unplugging one or the other. The two things taht worry me (from HDD Health) are the spin up time on the one. The threshold is 21 and it takes 98. Can that even be right? A minute and a half to spin up?

The numbers are ralative. There is no direct relationship to time. Every time the spin-up time exceesds a pre determined time the number is reduced. Every time the spin up exceeds the pre-determined time the number increases. So on your system the spin-up time can exceed the limits 77 more times before the disk is considered knackered. It has to be this way as most of the parmeters will vary depending on enviromental and operating conditions. Every hard disk will exceed its optimum spin-up time occasionaly if it has been left idle in a cold room for any length of time. Stuart
