I am getting repeated HDD error reported by the RAID systems. I am getting the HDDs replaced via warranty but this is happening too frequently tht I am thinking that something else is wrong. I have had about 5 HHDs failures in the last 4 weeks. As soon as I have rebuild one drive in the RAID 5 set up, the next one fails. It is not always the same port each either.
I have RAID0 with 2 x 1Tb WD drives for the O/S and RAID5 with 4 x 640 Gb WD drives for the data. All drives are SATA II. I use the Intel RAID controller which reports the disk read error and indicates to replace the drive. It is happening for both the RAID0 and RAID5. Could a fault with the motherboard be causing this problem?
