Using the RAID Utility
The RAID Utility allows you to configure your DriveStation Quattro 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.
Note that changing the mode of the drives in your Quattro will erase all data on
them! Back up any important data before using the RAID utility.
You should be connected to the DriveStation with a USB cable while running the
RAID utility. You may switch to an eSATA connection for normal use after the
utility has run.
You may launch the RAID Utility by clicking on RAID Setup Utility in the
DriveStation Quattro program group.
Or, you can launch the program from the Start menu:
