I have 2x Hitachi Deskstar P7K500 about a year old in RAID 1, md0 is boot and md1 is used by LVM.
Just recently I got a warning in X (FC11) that there are one or more disks failing.
I looked at the SMART attributes and I have errors on both drives:
/dev/sda errors logged: 140, UltraDMA CRC error count raw value: 500, relocated sector count: 0
/dev/sdb errors logged: 900, UltraDMA CRC error count raw value: 8700, relocated sector count: 1
So I think I should be replacing sdb soon however should I also replace sda?
