Hard Drive Replacement Procedure
Hard Drive Replacement Procedure
When an internal hard drive in the TeraStation has failed, the ERROR LED will glow red.
Open the front cover of the TeraStation and check the status LEDs. Any hard drive whose status LED is solid or
flashing red (or just flashing amber) is malfunctioning. A hard drive whose status LED is solid red can be
removed even if the TeraStation’s power is ON and replaced with a new hard drive (OP-HD series).
* 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.
* A flashing red (or amber) status LED denotes an active hard drive. Please perform the removal process on the
Web Admin of the TeraStation before replacing the hard drive.
* Hard drives can also be removed when the TeraStation is OFF since the drives are no longer active.
* Installing or removing a hard drive while the system is still running is referred to as a Hot Swap.
* The illustration contains a picture of the TeraStation ES (TS-XEL series). It shows the typical placement of the
different LED indicators on a TeraStation. Your product may be slightly different.

• The TeraStation is fragile. Handle with care. Do not drop or shock the TeraStation.
• The TeraStation weighs approximately 8kg (20lbs). 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 disassem

bling the TeraStation will void your warranty.
• To avoid damaging the TeraStation with static electricity, ground yourself by touching something made of metal parts such as a door knob or an aluminum
window frame. This will release any static charge.
• Use an OP-HD series hard drive approved by BUFFALO (sold separately), which has exactly the same hard drive capacity as one of the original drives, as a
replacement.
• 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 the top hard drive out and replacing it with the second hard drive may
cause data on the unit to be damaged or lost.
* It takes about 5 minutes before the message “RAID I18 ARRAY (either 1
or 2) Rebuilding” is displayed.
Insert it while the
tab is still open.
Push the drive into the TeraStation
and push the tab towards the back
of the TeraStation until you hear a
