@Chantetheactor How is the drive not working? Is the drive detected by disk utility? Is the drive making odd noises?
@etgalim Does the drive appear as RAW or Unallocated in disk management? It appears to be a logical failure and not hardware failure
@etgalim If drive is detected by Mac and mounts, then the issue will be with the PC or motherboard's TB port, have you contacted Asus?
@TimmyFeags Sorry to hear your having a problem with the product, is the drive detected by disk utility? @GTechStorage

G-SPEED Q - RAID Configurator

Using the G-Technology configurator, you can change the RAID settings to either RAID 0 (Stripe) or RAID 5 (Redundant Stripe). The RAID 0 setting will allow for an increased performance across both drives and display the maximum capacity available. The RAID 5 configuration allows you to write partial data across all drives. For example in a G-SPEED Q with 1TB (x4) drives, the end capacity would be 3TB of storage. The "missing" 1TB of space in this example is used to hold partial amounts of data in the event any 1 drive in the RAID fails.
