Replacing Drives on Another Unit Series Other Than the
TS51210RH Series
LEDs
Drives in the TeraStation show a green status LED during normal operation. If a drive fails, its error LED will glow red.
The following drive replacement examples use the case of the TS5410DN series.

Error LED
Glows red if a drive has failed.

Status LEDs
The failed drive's status LED will be glowing a steady red. A drive with a red status LED is ready to hot-swap.
Notes:
• Do not unplug a drive whose status LED is green instead of red. Dismount it first or shut down the TeraStation
before swapping a working drive. If you remove the drive without properly dismounting it, data may be lost or
the TeraStation may malfunction.
• If using the TS5210DF series TeraStations, use a Buffalo OP-SSD series drive as the replacement drive. For the
replacement drive of other series TeraStations, use a Buffalo OP-HDN series drive. The new drive should be the
same size or larger. If a larger drive is used, the extra space will not be usable in a RAID array.
• To avoid damaging the TeraStation with static electricity, ground yourself by touching something made of metal
before handling any sensitive electronic parts.
• After a drive is replaced, it will take about 30 minutes before normal file reading and writing are restored. Settings
may not be accessible during this period.
• Do not change the order of the drives in the TeraStation. For example, pulling out drive 1 and replacing it with
drive 2 may cause data to be corrupted or lost.
• If the LCD panel does not change after a new drive is installed, click Rediscover Drive in Settings.

Back up the saved data to another place before replacing the failed drive. If one or more drives fail during the
drive replacement, data can no longer be retrieved from the TeraStation.
