When a message asks you to confirm you want to partition
the disk, click on the “ Partition ” button. This may take a
couple of minutes, depending on the size of the drives in your
RAID storage. When the partitioning is complete, icons for
each new partition show up on your desktop. They are now
ready to use.
2.4.2.4 Make A Bootable RAID Volume
You can follow the following procedures to add ARC-8050T3U
RAID volume on Intel-based Mac bootable device listing.
1. Set the BIOS selection in System Controls: Advance Configu-
ration to “UEFI” option for Intel-based Mac boot.
2. Download macOS Sierra and follow the https://support.apple.
com/en-us/HT202796 link “How to set up and use an external
Mac startup disk”.
3. Mac doesn’t see devices that have Option ROM firmware until
you load the firmware by pressing “Option-Shift-Command-
Period” at the Startup Manager window.
4. Do this each time you want to start up from ARC-8050T3U.
2.4.2.5 Unmounting RAID Volumes
To avoid possible data corruption, Areca recommends that ARC-
8050T3U RAID storages volume(s) be properly unmounted from
the computer prior to turning off the RAID storage or safely
removing the Thunderbolt interface cable.
1. Drag RAID storage volume(s) icon to the trash. The Trash will
turn into an Eject arrow. This will assure that all data is
properly cleared from the system memory before the volume
is removed.
2. When the volume icon disappears from the desktop, RAID
storage can be disconnected from the computer.
