Hard Drive Failures in RAID System
Posted on 2004-10-14
This is sort of a continuation of a previous post I had.
Problems have reoccured. We are using Adaptec's verify media on all of our disks. So far all of them have FAILED except for one which is now 98% complete. That one was our hot spare and never actually used in the array. One of the ones that failed had just been repalced into the array.
Motherboard: Asus PU-DLS, firmware build 1006
RAID card: Adaptec 2810SA, lastest firmware
Hard drives: Seagate Barracuda 7200 120gb ST320026AS
Power Supply: Antec 550W
Raid configuration: RAID 5, 6 drives (5 in array, 1 hotspare)
We have a UPS system. Basically problems had reoccured and Adaptec said a hard drive had failed, Windows would completely stop responding for no reason (nothing in the event log), rebuilds to a new drive failed. And now we have started verifying media on each drive.... all but this one have failed so far (4 total failures, with two more to test--which includes the two drives we previously pulled and replaced)
Looks like are going hard drive shopping. But question is: What is causing these drives to fail??? We don't want to replace them only to have it happen again. Could they all have gotten bad sectors due to a specific event? Or is something in the hardware causing this?
I realize this is a crazy complex question, but we are going crazy here. We would appreciate greatly your help.
