OS: windows 7 ultimate 64 bit
RAID controller: Adaptec 3805 Raid6 8 2TB disks.
Adaptec storage manager shows bad stripe, 3 times I rechecked all hard disk drives (once from adaptec bios and twice from adaptec storage manager) and it didn't find any problems with the hard disks. Could the bad stripe be caused by windows?
How can I know if any hard disk drive needs replacing if it doesn't show any drive errors? What should I do?
