@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
