To remove a hard disk, select the disk you want to disconnect and
click Remove Disk.
After performing the procedure to remove the hard drive, taking it off
physically, and replacing to another hard drive, click here to have the
TeraStation recognize a drive again without restarting the unit.
This is displayed when clicking the name on the RAID array Screen.
If you have not set RAID, you can select from RAID 5, RAID 1, RAID 10,
and RAID 0 for TS-XL and TS-XEL series TeraStations, RAID 1 and RAID
0 for TS-WXL series TeraStations. If you do not select from any of the
above, the unit is used as a normal mode (4 hard drives).
Disk Structure:
Displays the hard drives that consist of RAID. To configure RAID,
check the hard drives you are going to use, select RAID mode, and
click Create Raid Array.
• To configure (build) RAID 1, click 2 drives you are going to use and
insert check marks.
• To configure (build) RAID 10 and RAID 0, click all drives and insert
check marks.
* TS-WXL series TeraStations cannot be set to RAID 10.
• To configure (build) RAID 5, click all drives or 3 drives you are going
to use and insert check marks.

• When delete RAID composition, click Delete RAID Array.
* Changing or deleting RAID settings will erase all data in the
hard drive. Back up your important data before performing any
operations described above.
* If you have a hard drive in the normal mode while building RAID 5
(3 hard drives) or RAID 1, it can be set as a spare by clicking Set to
spare-disk. If it has already set to a spare drive, click Set to normal
disk to set it to the hard drive in the normal mode.
* Set to spare-disk will not be displayed on TS-WXL series
TeraStations.
When there is an error on RAID Array, the system will be shut down
automatically to protect data (This feature is only for RAID 1, 5 or
10. This does not work while in normal mode or RAID 0). The default
setting is Not shut down.
