Check if the following logs are shown:
- The message “disk drive x failed or is unplugged” is shown on [System Administration]> [System Logs] (requires admin access to the web administration page of the NAS).
- The message “disk drive x failed or is unplugged” is shown on the LCD panel (ifavailable).
- A disk error message is shown on [Disk Management] > [Volume Management], forexample, “no disk”.
- RAID 1, RAID 5, RAID 6:Replace the failed hard disk drive(s) with new one(s). Turn on the Turbo NAS after installing the new hard disk drive(s). The Turbo NAS willperform RAID rebuilding. If RAID rebuilding is successful, the Turbo NAS will run properlyagain and the RAID data protection will be active.
RAID 10:If only one hard drive fails or two non-adjacent hard drives fail, replace the failed hard disk drive(s) with new one(s). Turn on the Turbo NAS afterinstalling the new hard disk drive(s). The Turbo NAS will perform RAID rebuilding. If RAIDrebuilding is successful, the Turbo NAS will run properly again and the RAID data protectionwill be active. If two adjacent hard drives fail in a RAID 10 volume, the data cannot berecovered anymore. Please replace the hard drives and create a new disk volume withthe new hard drives.
Note:It is recommended to replace the failed hard disk drives with new ones of thesame brand and same model. The RAID configuration cannot be rebuilt if the number of failed hard driveshas exceeded the maximum limit. The disk data will be lost in such case.
Single disk volume, JBOD, RAID 0:Replace the damaged hard disk drive(s) and then restart the Turbo NAS. Upon successful system startup, login to the Turbo NAS asan administrator. Go to “Disk Management” > “Volume Management” to configure thedisk volume. The newly installed hard disk drive(s) will be formatted and all the diskdata will be cleared.
Note:The data on the damaged hard disk drive(s) cannot be recovered.
Replacing the failed hard drive:
- Take out the disk tray.
- Remove the hard disk drive from the disk tray. Check if the hard disk drive is damaged. (Unplug the possible damaged hard disk drive and insert it to another Turbo NAS or machine(if any) to check if the hard disk drive can be read.)
- Replace the damaged hard disk drive with a new one.
Disk checking after replacing the failed hard disk drive:
- Turn on the Turbo NAS.
- Make sure no disk error message is shown on the LCD panel (if available).
- Login the Turbo NAS as an administrator.
- Check the disk status on [Disk Management] > [Volume Management]. If themessage “Not initialized” is shown, the hard disk drive is installed correctly.
- To configure the new hard disk drive as single disk volume, initialize the hard disk driveby the web-based interface.
- If the disk volume is configured as RAID 1/5/6, the NAS will rebuild the RAIDconfiguration upon successful restart. Make sure the NAS works properly and noerrors are shown after RAID rebuilding.
