Safety & General Use
Backup Your Data
The disk drives contained in your G-RAID with Thunderbolt device are delicate electronic
instruments and are susceptible to damage due to excessive physical shock. Under no
circumstances will G-Technology be held liable for the recovery or restoration of lost data. Any
loss, corruption or destruction of data while using a G-Technology drive is the sole responsibility
of the user.
Make Two Backups
To help prevent the loss of your data, we highly recommend that you keep TWO copies of your
data in separate storage locations. Keep one copy on your G-Technology drive. Keep a second
copy on your internal hard drive, another G-Technology drive or a form of removable storage
media. If possible, it is advisable to keep your data in two physically disparate locations for
added safety.

About Your G-RAID®with Thunderbolt™
Introduction
Thank you for purchasing G-RAID with Thunderbolt from G-Technology. The G-RAID with
Thunderbolt is a high-speed, low-cost RAID that provides an ideal storage solution for
content creation professionals. With its unique industrial design and all-aluminum housing,
G-RAID with Thunderbolt is the de facto standard for many post-production facilities
worldwide.
G-RAID with Thunderbolt features dual Thunderbolt 2 ports and a USB 3.0 interface. When
connected via the Thunderbolt interface, G-RAID with Thunderbolt provides data transfer
rates up to 440MB/second to support the most demanding professional content creation
applications such as Final Cut Pro®, Avid® Media Composer and Adobe Premiere®.
With its built-in RAID controller, the G-RAID with Thunderbolt is not tied to a single workstation
and can be easily transported for use in the edit bay or on the road. The unit contains an
internal RAID controller and can be congured in RAID 0 (Performance), RAID 1 (Protected) or
JBOD (Just a Bunch of Disks) mode.
In the RAID 1 or JBOD mode of operation, if a single hard drive failure occurs, your data will still
be safe and accessible (in RAID 1 all your data is safe, whereas in JBOD all your data stored on
the good drive is safe).

About Your G-RAID®with Thunderbolt™
Power, Activity and Failure LEDs
G-RAID with Thunderbolt contains LEDs for power, drive activity and drive failure. The “G”LED
on the front panel of the enclosure indicates Power (White) or RAID Failure (Red). There are also
Drive Activity LEDs and Drive Failure LEDs located on the drive modules.
The following table explains the meaning of each combination of LEDs on the drive.
State Power LED
(Front Panel)
Drive Activity
(Drive Module)
Drive Failure
(Front Panel)
Drive Failure
(Drive Module)
System Initialization Flash White On Flash Red Off
System Ready On On Off Off
Disk Activity On Flash Blue Off Off
Disk 1or Disk 2 Failure (RAID 0) Off Off Red On Purple On
Fail Safe Mode (RAID 1) Disk 1 Failure Off Off Red On Red On
Fail Safe Mode (RAID 1) Disk 2 Failure Off Off Red On Red On
The power light will glow when power is applied. The drive activity LED’s on the drive modules
will ash as data is transferred to or from the hard drive.
In the event of a disk drive failure, the RED drive failure LED located on the front panel will
illuminate. In RAID 1 mode - the red light on the drive module indicates the failed drive. If a drive
failure occurs in RAID 0 mode then the LED in the front panel turns constant RED.
• If congured in protected RAID 1 mode, all the data stored on the system will be intact.
• If congured in JBOD mode, only the data in the bad drive will be lost; the rest of the data
will be intact.
• If congured in RAID 0 mode, all data will be lost.
Please contact Technical Support for help if the “G” logo or drive LED is blinking or solid
RED, indicating drive failure.
