Introduction
The DriveStation is a fl exible, easy to use hard drive. It can work as either a standard external
USB hard drive, or as a network attached storage device, accessable to many computers at
once. This user manual is intended to assist you in confi guring it.
Because we’re constantly updating our products, the images and text in this manual may vary
slightly from the images and text displayed by your DriveStation. These changes are minor
and should not affect the ease of setup adversely. As time passes, future user interfaces,
updated software, and later versions of this manual may be freely available for download at
our web site www.buffalotech.com.
For best results, attach the DriveStation to an uninterruptable power supply (UPS). Back
up all your stored fi les regularly.

Network Settings
In most networks, DriveStation will get its IP Address
automatically from a DHCP server. You may disable DHCP
here if you would rather set a static IP address manually.
If DHCP is disabled and an IP Address is not set manually,
it will default to 192.168.11.150 with subnet mask
255.255.255.0. In that case, change your PC’s IP address
to 192.168.11.xxx and subnet mask to 255.255.255.0 to
access the DriveStation or use the DriveNavigator Wizard.
The DriveStation’s IP Address, Subnet Mask, Default
Gateway Address, and DNS Server address may all be
entered manually under IP Address Properties.
Click Apply after making any changes.

14
Sleep Mode
To save power, the DriveStation can be set to go into sleep
mode after 10 - 60 minutes of inactivity. Theis sleep mode
setting only works when the DriveStation is connected via
LAN. To use sleep mode while the DriveStation is in USB
mode, install the eco manager tool, located in the Tool/eco
folder of your CD.

15
Disk Management
Here, you may initiate a disk check that
scans your DriveStation’s hard drive for
errors. Also, you may reformat the hard
drive from here. Reformatting the drive
erases all data from the drive, so make
sure that your backups are up to date
before reformatting the drive.

16

a password twice and click apply. Once the admin account
is password protected, you may password protect your
