Maintenance for Your Drive
Replace a Failed Drive Module
The internal components of G-RAID with Thunderbolt continually monitor the health of each of
its disk drives. In the event of a drive failure, a visual alarm will appear. Read more in Activity and
Failure LEDs.
RAID 0: If G-RAID with Thunderbolt was congured in RAID 0 (Performance) mode, a drive
failure will result in data loss.
RAID 1: If G-RAID with Thunderbolt is congured as RAID 1, a single drive failure will not result
in data loss. However, the array is now in a degraded or unprotected state, and the failed drive
should be replaced as soon as possible to avoid data loss.
Read more in Supported RAID Modes.

1. With the unit powered on, the ashing RED LED will indicate which drive module failed. For
