If you are using RAID 1, RAID 5, RAID 6, RAID 50 or RAID 60 you can easily replace
a damaged hard drive in the Thecus IP storage while keeping your data secure with
the system’s automatic data recovery.
Hard Drive Damage
When a hard drive is damaged and data in the RAID volume is corrupted, the
system OLED will display a warning message and the system will beep.
Replacing a Hard Drive
To replace a hard disk drive in the Thecus IP storage:
1. Remove the tray with the damaged hard disk.
2. Unscrew the damaged hard disk and remove it from the tray.
3. Slide a new hard disk into the tray and fasten the screws.
4. Insert the hard disk tray back into the Thecus IP storage until it snaps into
place. You can also lock it with a key if desired.
5. The LED will blink green when the HDD is accessed.
RAID Auto-Rebuild
When using RAID 1, 5, 6, 10, 50 or 60 on the Thecus IP storage, you can use the
auto-rebuild function when an error is detected.
1. When a hard disk fails the system beeps and/or an email notification is sent
to the specified receivers.
2. Check the OLED to see which disk has failed.
3. Follow the steps mentioned above to replace the failed hard disk.
4. The system automatically recognizes the new hard disk and starts the
