Disks
Format Disk Format the additional hard disk installed to the TeraStation and the USB connector. Data
will be completely erased if the disk is formatted. Please use extra caution not to loose your
important data. The time required to format a disk will vary depending on the space to be
used (a few minutes).
* You cannot format a disk when you have set up a backup job.
Warning: Do not format a drive if the TeraStation is congured as a backup device for
another TeraStation.
* Format type

It is recommended when you may reconnect to TeraStation and use it.
• Supports both Reading/Writing.
• Supports Journaling File System.
• Takes for a long time to format (a several minutes or more).
• Less space is available than XFS after formatted.

This format is recommended when you use the additionally installed
hard disk at the TeraStataion.

TeraStation fails.

use to connect to Windows 7/Vista/XP/2000, or Windows Server2003/
Server2008.

• Read-only (not writable during backup or replication either).
* GPT partitions (64 bit) are recommended for connected USB hard drives of 2.2 TB or larger.
Other types of partitions will not address the full size of larger drives. GPT partitions are
supported by Windows 7, Windows Vista, Windows Server 2003 SP1 or later, Windows Server
2008, Mac OS X 10.4 or later, and Bualo TeraStation and LinkStations (e.g. TS-XL, TS-XEL,
TS-WXL, LS-XHL, and LS-CHL series). Please note that other operating systems (including
Windows XP) may not detect GPT partitions correctly. To read hard drives larger than 2.2 TB
from Windows XP, either use a proprietary GPT solution, or use multiple partitions smaller
than 2.2 TB.
