Changing RAID Modes
RAID Arrays
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.
TeraStation User Manual |
18 |
• 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 file transfer speeds are slower than usual until the RAID array is rebuilt.

Adding an External Hard Drive
Connect an External Drive
Your TeraStation includes 2 USB connectors (3 if it’s a TS-RXL). You can connect a Buffalo external hard drive to it for backup or extra storage.
Connect the external drive as shown below. If the hard drive is already formatted, it will be detected automatically. If it is not formatted, format it from within the Web Admin interface (page 28).
One external hard drive may be connected to each USB port on the TeraStation. USB hubs are not supported.
Warning! Do not unplug the drive from the TeraStation without dismounting it first. Turn to page 30 for directions on dismounting a connected drive.

If the drive properly connected, usbdiskX is added to the TeraStation’s shares on the network, where X is the # of the drive.
•Note: Files that are automatically created by Mac OS X cannot be backed up to a FAT 32 drive because they contain characters that are not allowed in FAT 32.

Formatting the External Drive
•A format deletes all data from a hard drive. Be careful! Back up any important data on a drive before formatting it. It will take a several minutes to format a drive.
•Shared folders cannot be accessed during formatting.
•Do not turn off or disconnect power to the TeraStation while formatting a hard drive.
•If Power Mode Switch is set to AUTO, then the TeraStation will turn off when the format is finished.
•To erase all data on a disk, choose [System] - [Restore/Erase].

Set Access Restrictions on the External Drive
You can set the access restrictions on the new drive. Use the procedure on page 42 to set the access restrictions.
Note:
Even if a shared folder is not visible, you can still format the drive, run a disk check, and back up to the new drive.
Restrictions
•The TeraStation supports many types of USB devices including USB storage devices, card readers, digital cameras, and USB printers. Other devices are not supported, such as USB hubs, card readers that recognize multiple memory cards, and USB mice and keyboards.
•You can connect up to 2 hard drives to a TeraStation via its USB connectors (3 for a TS-RXL). Only Buffalo drives are supported.
*The TeraStation may not recognize a hard drive whose power mode is set to AUTO. Set the power mode to MANUAL for drives connected to the TeraStation.
*Direct Copy doesn’t work with the HD-DU2 series DriveStation unless it has been reformatted.
*The TeraStation can supply bus power to a single external drive only. For multiple drives, or if you experience power problems, connect an AC adapter to each hard drive.
•Only the primary partition of the hard drive connected via USB connector will be recognized. Secondary and other partitions will not be recognized.
