@Reuben_Wu so the port on the drive is defective, you will want to submit an RMA to have it replaced under warranty
@Reuben_Wu have you tried another cable? can you duplicate the issue from another computer? might be a bad cable
@Robbie_McKane At this time there are no plans for a G-Raid Mini w/Thunderbolt - It is possible this may change in the future.
@MrToddClark 1 year warranty - Warranty Exp: 2013-07-30

G-RAID mini - RAID Configurator

Using the G-Technology configurator, you can change the RAID settings to either RAID 0 (Stripe) or RAID 1 (Mirror). The RAID 0 setting will allow for an increased performance across both drives and display the maximum capacity available. The RAID 1 configuration allows you to write the same information to both drives providing a better level of protection in the event one drive fails, however RAID 1 will reduce the capacity of the drive to 50% of the advertised capacity.

G-RAID mini with USB 2.0 uses two different types of chipsets Oxford and JMicron. Should you have a serial number with a "JM" at the end, please download the JMicron chipset utility. If your G-RAID mini does NOT have a "JM" at the end of the serial number, please download the Oxford chipset utility.

G-RAID mini with USB 3.0 uses the JMicron chipset, please download the JMicron chipset utility.
