Hi there,
I have a RAID10 array made up of 4 x 500GB Western Digital Caviar SE16 SATA-II (WD5000AAKS) disk drives. Roughly once a day, my RAID controller spontaneously decides that the RAID volume needs to be re-built; I have no option but to let it rebuild. The SMART status of all four disks is "NORMAL". On one occasion, the RAID controller claimed that the 4th disk in the array was broken and that I should replace the disk. But, after a few minutes, it decided that the fourth disk was absolutely fine and started rebuilding the array.
My RAID controller hardware is the built-in RAID function of the Intel P35 chipset. My motherboard is a Gigabyte P35-DQ6. My RAID software is the Intel Matrix Storage Console (v7.6). As far as I'm aware, I'm running the latest BIOS and drivers. I'm running WinXP32 SP2.
I've tried running the Western Digital diagnostic programme but it can't see the individual drives in the RAID array and I don't have the option of disabling the RAID array (i.e. I have 1TB of data on my RAID array that I need to keep on my RAID array).
Sometimes the computer will freeze for a few seconds while I'm using it and immediately after the computer comes back to life, the RAID controller software will say that it needs to re-build. I don't know if the freezing causes the RAID controller to get confused or if the RAID controller causes the freeze!
Any help would be really, REALLY appreciated! I need my computer to be healthy again!
I have two hunches: the first is that my fourth drive really is dying and that I should replace it. My second hunch is that my cheapo-PSU is doing something ugly and should be replaced.
Unless anyone has any better ideas, my plan of action would be to remove the fourth drive from the array and run an exhaustive set of tests on the drive.
Thanks loads,
Jack
