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. 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 configured as a backup device for
another TeraStation.
* Format type
TeraStation can format or recognize the following format types:
Format type
Descriptions
EXT3
(USB hard drive
only)
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.
• More files in 1 folder, slower the access space.
* Use EXT3 Reader included in this package when reading data directly
connected to your PC.
XFS
(USB Hard Drive/
TeraStation
Internal Hard
Drive)
This format is recommended when you use the additionally installed
hard disk at the TeraStation.
• Supports both Reading/Writing.
• Supports Journaling File System.
• More space is available than XFS after formatted.
• Access speed will not degrade even though more files in 1 folder.
This is not supported by legacy TeraStation (such as HD-LAN, HD-HLAN,
HD-HLWG, HD-HGLAN Series).
* You cannot read data by directly connecting a PC.
FAT32
(USB hard drive
only)
We recommend this format type when you want to connect the hard
drive to your PC to view data in it.
You can still connect the hard drive to Windows PC in case that the
TeraStation fails.
• Supports both Reading/Writing.
• Cannot copy, backup, or replicate data with more than 4 GB per file.
• Cannot use some characters which are used in Mac OS such as [:].
NTFS
(USB hard drive
only)
Cannot format from Settings. It is Read-Only. Be able to use to connect
to Windows 8/7/Vista/XP/2000, or Windows Server2003/Server2008.
• Read-only (not writable during backup or replication either).
HFS+
(USB hard drive
only)
Cannot format from Settings. Read-Only.
Can be used to connect to OS X 10.3.9 or later.
• 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 8, Windows 7, Windows Vista, Windows Server 2003 SP1 or
later, Windows Server 2008, OS X 10.4 or later, and Buffalo TeraStation and LinkStations
(e.g. TS-XL, TS-XEL, TS-WXL, LS-XHL, and LS-CHL series). 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.
