Caution
With some models of hard drives, if the Master hard drive fails, it
may cause the Slave hard drive to be unrecognized by the
computer's operating system. Where a RAID 1 (Mirroring) array
exists on the Master/Slave pair, this condition may cause the
operating system to freeze.
Do NOT create a RAID 1 (Mirroring) array with two Parallel ATA
hard drives using the Master/Slave arrangement on Channel 3
(the Parallel ATA port).
You can create a RAID 1 (Mirroring) array by combining hard
drives on:
•
Channels 1 and 2 (Serial ATA only)
• Channels 1 and 3 (one Serial, one Parallel)
• Channels 2 and 3 (one Serial, one Parallel)
