SuperTrak EX Series User Manual

RAID 0

Because RAID 0 logical drives are not fault-tolerant, there is no way to rebuild the logical drive when a physical drive fails.

See “Managing Physical Drive Problems” on page 60 to determine if there is any way to salvage the physical drive and restore your logical drive.

If the physical drive cannot be salvaged, replace the drive, then create a new logical drive and copy your data to the logical drive from a backup source.
