Seagate SATA HDD beeping

I have two 160GB Seagate SATA drives in a RAID 0 configuration. When this problem first started, they would beep every one in a while, causing about a 2 second hang. It's now to the point where they are only intermitently seen by the system (even the RAID controller).

Are both the drives bad? Or is this a problem with the motherboard? I've also seen some people who had this problem said it was their power supply voltages, but mine aren't that bad (12V+ is 12.16V, 5V+ is 4.35V).

Have you run the drive diagnostic on it?

Your 5V voltage is kinda low for me.
I would run the utility on the drives as DoTheDEW335 has suggest. Be sure to run it on the drives individually. Not as a RAID.

If the raidcontroller is not always seen, my bet would be it's either the voltage or controller...
if it IS the controller, you'll need the exact same (chip) to recover the raidvolumes...(sometimes similar chip will work too)

Good Luck,

The SeaTools program is unable to see the drives either. Is there some way I could test the raid controller by itself? I know I could test the PSU by using another power supply that I know works, but I'm not sure if I have any good ones laying around here.

Blue Rishi, when you talked about replacing the chip, did you mean prying off the old one and putting on a new one, or just getting another motherboard with the same chip on it? Because with the number of small pins coming out of the chip, it'd be an almost impossible soldering job.

It does sounds as if you have a bad SATA controller. I don't think he means replacing the chip itself but either getting another MB with same SATA controller or getting a PCI card with the same type of controller chip as the MB has.

crazijoe is right. I don't know any software that will allow you to test the controller by itself (I have searched, believe me). If you find any software (pref. dos-based), please let me know!
You should test the drives with another board/controller only to see if it's being found, if it's not the drives, psu or the bios/firmware, then it must be the controller...
Btw, there is software for recovery of raid volumes: http://www.runtime.org/raid.htm

I think the points should be split.
