If a drive in the TeraStation fails, the Error LED will glow red.  Open the front cover and check the Status 

LEDs. The malfunctioning drive's Status LED will be glowing red. This drive may be hot-swapped.  Replace 

with a Buffalo OP-HD series drive of the same size.

 

Only failed drives may be hot-swapped.  If you need to remove a drive that has not failed and 

whose Status LED is not glowing red, either shut down the TeraStation, or dismount the drive in 

RAID Builder. Once the TeraStation is shut down, or the drive is dismounted, then it is safe to 

replace the drive.

 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 TeraStation is fragile.  Handle it 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 drives should be Buffalo OP-HD drives of the same capacity as the originals.  These drives are available from www.buffalotech.com.

 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.

 In a RAID 1 configuration, the boot drive (C:) consists of the first and second hard drives from the top. Do not replace both of these hard drives at 

the same time.

 If a hard drive is replaced while saving a file, the file can be corrupted. Be sure that the saving operation is completed before replacing the hard 

drive.
