Hard Drive Replacement Procedure
Hard Drive Replacement Procedure
When a hard drive in the TeraStation has failed, its Error LED will flash red.
Open the front cover of the TeraStation and check the Status LEDs. Any hard drive whose Status LED is lit or flashing
red is malfunctioning. You may hot-swap a hard drive whose Status LED is lit. The replacement drive should be a
Buffalo OP-HD series drive of the same size.
・ Do not unplug any hard drive whose Status LED is not lit red. If you remove the drive, data may be lost or the
TeraStation may malfunction.
・ The Status LED for active hard drives will be flashing red. Please dismount an active hard drive in the TeraStation's
Web Admin interface before hot-swapping it.
・ If the TeraStation is off, drives may be replaced without dismounting them first.
・ Installing or removing a hard drive while the system is still running is referred to as a hot-swap.
・ The Status LED of a drive configured as a hot spare will be lit green. This drive may be removed.
・ After a hard drive dismounted from the Web Admin interface is removed, its Status LED will be lit green.
・ If a drive fails while changing to RAID 1 with RMM (RAID Mode Manager) trying to preserve data, the data transfer may lock up. If this happens, remove both
drives and restart the TeraStation. With the power on, mount the drives and format from the Web Admin interface. All data on the drives will be lost.
・ The TeraStation is fragile. Handle with care. Do not drop or bump the TeraStation.
・ Use caution when handling the unit in order to avoid personal injury.
・ Never disassemble any parts while you are replacing a hard drive unless instructed to do so in this manual. Any malfunction or damage caused by
disassembling the TeraStation will void your warranty.
・ To avoid damaging the TeraStation with static electricity, ground yourself by touching something made of metal before handling any sensitive electronic parts.
・ Replacement drive should be a Bu alo OP-HD series (sold separately) with the same capacity as the original drives.
・ Do not use any hard drive that has been used in another TeraStation/LinkStation or another computer as a replacement drive. If you do, data on the unit may be
damaged or lost.
・ Do not change the order of the hard 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 even though a hard drive was installed, click [Rediscover Disk] in the Web Admin interface, then perform the RAID rebuilding,
format, or other process.
・ In the TeraStation's messages on the LCD panel, "Diskx" is hard drive # X and "RAID ARRAYx" is RAID array # X.
・ After a drive is replaced, it takes about 30 minutes before normal le reading and writing is restored. The Web Admin interface may not be accessible during
this period either.
Drive Replacement
(using a redundant RAID mode such as RAID 1, 5, or 6 with auto-shutdown disabled)
This section describes the process of replacing a hard drive while the TeraStation is still on. To replace the failed hard drive:
1
Before replacing the hard drive, update your rmware to the latest
version. You can download the latest version of the rmware from
www.bu alotech.com.
Note:
To see your current rmware version, check the LCD panel on the front of
the TeraStation. Press button to cycle through di erent displays
until the version number is displayed. You can also identify your
rmware version from NAS Navigator2 or the Web Admin interface.
2
Open the front cover with the included key.
3
Push the cartridge tab of the failed hard
drive (denoted by the glowing red Status
LED) to the left and swing the lock around to
the left.
Hard drives without red Status LEDs lit are
still on. Do not unplug or remove them. If
you do so, data may be lost or the
TeraStation may malfunction.

You have now completed the hard drive replacement process.
Pull out the hard drive cartridge and remove it
from the TeraStation.
Insert the OP-HD series hard drive (sold
separately) into the empty slot from Step 4.
Slide the drive in with the locking mechanism open.
Slide the drive into the TeraStation, then swing
the lock back down until it clicks into place.
When the replacement hard drive is recognized, the Status LED will flash
and the front LCD panel of the TeraStation will display the message, "Press
FuncSW I31 New Diskx ready".
Hold down the Function button on the front of the TeraStation for 3
seconds until it beeps. The TeraStation will start rebuilding the RAID array
automatically.
It takes about 5 minutes before the message "RAID I18 ARRAYx Rebuilding"
is displayed.
All data on the newly installed OP-HD series hard drive will be erased
during this process.
