Rebuilding A Mirrored Array - Western Digital WD Serial ATA RAID Controller User Manual

Rebuilding a Mirrored Array

If you receive an error message when booting your system from the WD SATA RAID
Controller's BIOS, this may mean that one of the drives attached to the controller may be
malfunctioning, or the array may have become unstable. Immediately test the drives to
determine which drive is causing the error and replace if necessary. Once the drive is replaced
or the drives are deemed correct and free of defect, use the steps listed in this section to
rebuild the Drive Array.
1. On bootup, the WD SATA RAID controller's BIOS will display an error message
identifying which drive has failed. Please take note of this drive and document for future
use.
