Press and hold the function button on the front of the TeraStation for three seconds until it beeps.
The replaced drive will be automatically registered as a hot spare. To use the replaced drive as a normal drive rather
than a hot spare, navigate to Drives > RAID and click the RAID array, select the new drive, and click Set as a normal
disk.
Note: If a drive fails in the RAID array before it is rebooted, the hot spare will not automatically replace the failed
drive. In this case, follow the procedure below to repair the array.
(1) From Settings, navigate to Drives > Drives.
(2) Click the drive that was configured as a hot spare, then click Dismount Disk.
(3) Click Rediscover Disk.
(4) Navigate to Drives > RAID.
(5) Choose the RAID array to repair.
(6) Click the drive that was previously configured as a hot spare, then click Recover RAID Array.
This will rebuild the RAID array.
Replacing a Media Cartridge
Drives configured as media cartridges may be removed and moved to a different TeraStation for use. Before
unplugging the drive, dismount it in Settings or shut down the TeraStation.
Replacing a Non-Malfunctioning Drive
Do not replace a drive that is not malfunctioning (unless it has been converted to a media cartridge).
If you must change a drive that is not malfunctioning, either first dismount it in Settings, referring to the
"Dismounting Drives"
section above or shut down the TeraStation before replacing the drive. If you need to replace
more than one drive at the same time, replace the drives one at a time to preserve your data. When replacing the
non-malfunctioning drive, the RAID array will function as below:
Operating in RAID 0 Mode
All data on the RAID array will be deleted after replacing the drive. You will not be able to use the TeraStation until
you delete and rebuild the RAID array with the new drive.
Operating in JBOD
All data on that drive will be deleted after replacing the drive. You will not be able to use the TeraStation until you
format the new drive.
Operating in a Redundant RAID Mode
If you are using a redundant RAID mode such as RAID 1, 5, or 6, the RAID array will be in degraded mode after
replacing the drive. You will not be able to use the TeraStation until you rebuild the RAID array with the new drive.
RAID Array Cannot Be Rebuilt after Formatting a New Drive
With a redundant RAID mode, a drive format is not necessary when recovering the RAID array. If you format the
drive, the RAID array cannot be recovered. In such a case, follow the procedure below to make a replaced drive
unformatted.
