TeraNavigator Setup
To congure your TeraStation, insert the TeraNavigator CD into a Windows computer on the network and follow the
directions, or use the following procedure.
Note:
Use LAN Port 1 for initial setup. After setup, you may connect a second cable to LAN Port 2. If used, congure the IP
address of LAN Port 2 at [Network] - [Setting] - [IP Address Settings] in the Web Admin interface or NAS Navigator2.

The following settings changes are recommended.
Notes:
• By default, the TeraStation will attempt to use an NTP server to set the time.
• NTP may not be usable in some network environments.
• Please read the terms of use for Internet Multifeed Co. at www.jst.mfeed.ad.jp. Internet Multifeed Co. is the
group that manages the NTP Server at www.jst.mfeed.ad.jp. Internet Multifeed Co. is not responsible for any
loss or damages caused by this service.
• BUFFALO is not responsible for any loss or damage caused by using of this service, stopping the service, or
missing service.
• If your TeraStation fails to automatically obtain the time from NTP Server, verify the settings for the DNS server
address of the TeraStation. You must set a primary DNS server address to specify an NTP server by host name.
Otherwise you will have to specify the DNS server by IP address. You can change the DNS server settings at
[Network] - [Settings] - [IP Address Settings] in the Web Admin interface.

Chapter 3
Changing RAID Modes
TS-XL, TS-XEL and TS-RXL series TeraStations default to RAID 5 mode (4 hard drives), TS-WXL/R1 series default to RAID
1 mode, and TS-WXL/1D series default to Normal mode. The characteristics of each type of RAID are described below.
If you change the RAID mode, all of the data on the hard drive is deleted. Always back up any important data before
changing the RAID mode.
Note:
• In this document, “recovery” means putting the TeraStation back to the state it was in before the malfunction
happened. It does not mean reading data from failed hard drives.
• RAID 5 mode (4 hard drives) (Default for TS-XL, TS-XEL and TS-RXL)
Note:
TS-WXL/R1 and TS-WXL/1D TeraStations don’t support this mode, as they don’t have 4 hard drives.
Uses 4 hard drives as one array. It generates parity during writes, so access speeds are slower than other RAID modes.
Usable space is the sum of 3 hard drives’ space. If one hard drive in the array is damaged, you can recover data by
replacing the hard drive. You cannot recover data if 2 or more drives are damaged.
• RAID 5 mode (3 hard drives)
Note:
TS-WXL/R1 and TS-WXL/1D TeraStations don’t support this mode, as they don’t have 3 hard drives.
Uses 3 hard drives as one array. It generates parity during writes, so access speeds are slower than other RAID
modes. Usable space is the sum of 2 hard drives’ space. You can designate a 4th drive as a hot spare, which will boot
automatically if one of the drives in the array fails. If one hard drive in the array is damaged, you can recover data by
replacing the hard drive. You cannot recover data if 2 or more drives are damaged.
• RAID 10 mode
Note:
TS-WXL/R1 and TS-WXL/1D TeraStations don’t support this mode, as they don’t have 4 hard drives
RAID 10 combines 4 hard drives into a single array. Usable space is the sum of the capacity of 2 hard drives. Data is
written quickly and access speed is faster than other RAID modes except for RAID 0. Since the same data is written to 2
hard drives at the same time, if drive in a pair (1-2 or 3-4) is damaged, data can be recovered by replacing the damaged
hard drive. If both 1-2 or 3-4 hard drives are damaged, you cannot recover data.
RAID Arrays

TeraStation User Manual 19
• RAID 1 mode (Default for TS-WXL/R1)
Uses 2 hard drives as one array. You can use up to 2 arrays on TS-XL, TS-XEL and TS-RXL Series. The space you can use
is 1 hard drive’s space for each array. The same data is written to 2 drives at once. If a drive is damaged, data can be
recovered by replacing the damaged hard disk. If both drives in an array are damaged, data cannot be restored. You
can create an array and designate another drive as a hot spare (which will boot automatically when one of the hard
drive fails) in TS-XL and TS-RXL TeraStations. You can use 2 drives to create a RAID 1 array, use anther drive as a hot
spare, and use another as a regular drive, all at once.
• RAID 0 mode
This mode uses multiple hard drives as a single array. The disk space you can use is the total space of all hard drives
used. This is the fastest of the TeraStation’s RAID modes. If any hard disks are damaged, you cannot recover data.
• Normal Mode (Default for TS-WXL/1D)
This mode uses the hard drives inside the TeraStation as individual hard disks. It is sometimes referred to as JBOD. The
disk space you can use is the total space of all hard drives in the TeraStation. If a hard disk is damaged, you cannot
recover data from that drive.
Note:
During a recovery, the TeraStation’s front LED display shows “RAID ARRAY* Resyncing” and le transfer speeds are
slower than usual until the RAID array is rebuilt.
