DriveStation Setup

Installing the RAID Utility
By default, your DriveStation is configured in RAID 5 mode. If you’re willing
to trade some performance for better data security, Buffalo Technology
recommends RAID 5 mode, with its excellent balance of security and total
capacity. You may change your RAID configuration with the RAID Utility.
The DriveStation must be connected to your Mac with a USB cable while using
the utility. You may switch to an eSATA connection for normal use after the utility
has run.
The RAID Utility allows you to configure your DriveStation in several modes:
Normal Mode - Appears to your computer as four separate hard drives.
Spanning Mode - Appears to your computer as one large hard drive.
RAID 0 Mode - Appears to your computer as a single drive. Higher performance
than Spanning mode.
RAID 1 Mode - Appears to your computer as a single drive. The third and fourth
drives keep an exact copy of the first and second drives, for redundancy.
RAID 5 Mode - Appears to your computer as a single drive. Approximately 3/4 of
your total space is usable, yet you still have full redundancy.
Changing the mode of the drives in your DriveStation will erase all data on them!
Back up any important data before using the RAID utility.
To install the RAID utility, open the Mac folder on your DriveNavigator CD.
Double-click on RaidSetting.dmg to install the RAID utility.

6
Using the RAID Utility
Double-click the RaidSetting icon on your desktop.
Once launched, the RAID utility will briefly scan for
your DriveStation. This may take a few seconds.
The initial screen will show your current configuration.
To change the RAID mode, click RAID Settings and choose Change
Disk Structure.

7
Using the RAID Utility
Select the drive structure that you’d like to use. Click OK, Yes, and Yes.
Understand that this will erase any data on the drive!
After changing the RAID mode, you will need to use the Disk Utility to
format the new partition.

Support Tray Installation
If your equipment rack
supports equipment from the
front only, use the mounting
tray to provide the support your
DriveStation needs. Screw the
tray into into the rack with the
four screws provided and a #2
phillips-head screwdriver.
4x
Slide the DriveStation into the
tray. Secure it with the two
thumbscrews; one on each
side. You may use a fl athead
screwdriver to snug down
the thumbscrews, but do not
overtighten.

9
Your DriveStation is now secure and stable in
the rack!

FCC Warning
This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
Note on Format
By default, the DriveStation is formatted with FAT32, allowing use with
all modern operating systems. Unfortunately, FAT32 is limited to 4GB
files, making it unsuitable for use with many video editing and backup
software packages. If you plan to use the DriveStation with programs
that generate files larger than 4GB in size, use the Mac Disk Utility to
reformat your drive with a “Mac OS Extended” format.
