After accidently knackering my external backup drive by knocking it over, I decided to buy a couple of extra 1.5 tb drives to add to the two I already have and create a RAID 5 array on my ICH10, as I could do with a bit more storage anyway. Everything was going swimmingly until about two days after installation, intel matrix storage manager reported an error on one of the two new drives, however the array was still intact but had lost redundancy.
Fearing one of the two new drives was a dud, I marked the drive as normal, backed up the data elsewhere and rebuilt the array, which took about 60 hours. Again everything seemed to be fine until about 5 days later when the same thing happened again. This time the error was detected on one of the old drives, this seemed a bit coincidental that both drives would develop errors within days of each other, so I originally thought the controller might be faulty or that a recent overclock might have affected the southbridge chip somehow. But then I checked the windows defrag schedule, it had defragged that morning and was defragging every week.
Is it possible for a windows defrag to corrupt/cause errors on a RAID 5 array? Is there other software available (ideally free) that can perform sed function?
The second rebuild finished today, in the meantime I have disabled the defrag just to be on the safe side and will sit and wait to see what happens.
