Despite the avobe errors, is the RAID1 array going offline?
Can anyone please enlighten me to what it means; Am I about to lose a
disk?
It seems to be localized in just one of the disks (the one connected to
the third sata port). Hard to tell what's going wrong (software bug/error,
hardware error?), but I would start by replacing the sata cables for
both disks, just in case. I've found many weird issues with poorly
designed/bad quality sata cables that come bundled within motherboard pack.
