RAID 0 or RAID 1. If the Mercury Elite Pro Dual is set up as a span or as a RAID 0, the array must be reformat- ted before it can be used again. If the Mercury Elite Pro Dual is set up in independent drive mode, you do not need to reformat the existing drive or the new drive.
Then, simply verify that both ends of your cables are properly plugged into the computer and the Mercury Elite Pro Dual. If the Mercury Elite Pro Dual is still not working properly, try connecting to another interface (USB or Thunderbolt) and see if the device works properly.
To ensure that your files are protected and to prevent data loss, we strongly suggest that you keep two copies of your data: one copy on your Mercury Elite Pro Dual and a second copy on either your internal drive or another storage medium, such as an optical backup, or on another external storage unit.
