What To Do In The Event Of A Disk Drive Failure 

The internal components of the G-SPEED Q continually 
monitor the health of each of the disk drives. In the event of a 
disk failure, a visual alarm will appear. 

NOTE

: If G-SPEED Q was configured in a protected RAID 

mode (RAID 5), a drive failure will not result in data loss. 
However, the array is now in an unprotected state and the 
failed drive should be replaced as soon as possible to avoid 
data loss. If G-SPEED Q is configured as RAID 0, there will be 
data loss.

Follow the steps below to identify and replace a failed drive.

1. Locate the malfunctioning drive by visually inspecting the 
drive modules. If an amber LED is lit for a drive, it is the one 
that has failed.

2. Remove the failed drive 
by inserting the provided 
key in to the lock hole and 
gently sliding the drive 
module out of the 
enclosure.

WARNING: REMOVING THE 
WRONG DRIVE WILL RESULT 
IN THE LOSS OF THE ARRAY 

AND ALL OF THE CONTENT STORED ON G-SPEED Q.

4. Replace the failed drive with a new disk module (new drive 
modules can be purchased here) and secure it in place. Once 

the drive has spun up to speed, the drive will indicate that the 
array is rebuilding. The rebuild time is approximately 2 hours 
per TB.

Note

: You can continue using the G-SPEED Q even while the 

volume is being rebuilt, albeit at slower data rates.

5. Once the rebuild is complete, G-SPEED Q is back to Normal 
and protecting your valuable data once again.

Note

: It is good practice to keep at least one spare drive 

module on hand in case of a disk failure. This way, you can 
rebuild your array in hours rather than wait days for a new 
one to ship to you.

Disconnecting G-SPEED Q 

A great feature of G-SPEED Q is its ability to be connected 
and disconnected while your computer is running.  To 
prevent failures and/or data loss it is important to follow the 
steps below when disconnecting or “unmounting” the G-
SPEED Q from your computer. 
 
1. Before powering down and disconnecting G-SPEED Q, you 
must unmount the system by simply dragging the G-SPEED Q 
icon to the trash located in the dock. 
 
2. It is now safe to power off and remove G-SPEED Q from 
your system. 

Note

: you can also mount and unmount the G-SPEED Q in 

Apple Disk Utility.
