Troubleshooting
Should a Hard Drive Fail:
When using RAID1 or RAID5 - The failed drive will have a red light blinking in the STATUS/FULL
position of the front display. If you need to determine which drive has failed, restart the TeraStation
and watch which disk LED illuminates red. After replacing the failed drive, RAID will restore your
array.
When using Standard Mode - The failed drive will have a red light blinking in the STATUS/FULL
position of the front display. To determine which drive has failed, restart the TeraStation and watch
which disk LED illuminates red. After replacing the failed drive, all data on that drive will be lost.
Data on other dives should still be normally accessable.
When using Spanning Mode - All drives will have a red light blinking in the STATUS/FULL position
of the front display. Further troubleshooting will be required to determine which drive has failed in
the array. Data recovery is not possible by replacing a drive. After replacing the failed drive, you will
have to delete and recreate your RAID array to make the TeraStation usable again. All data on the
array will be lost.
If your TeraStation is still under warranty, contact tech support before replacing your hard drive.
Replacing your hard drive yourself may void your warranty. If your warranty has expired, you may
replace the hard drive with an exact replacement (available from Buffalo Technology), or with any IDE
drive of at least the same capacity as the failed hard drive.
