FAT32 Formatting Utility (Windows)

To install this application on your Windows computer, open the FAT32tool folder on the CD and then double click the fat-
32tool.exe file to run the FAT32 formatting utility.

Configuring the RAID Mode

This Verbatim 4-bay RAID drive can be configured to one of three RAID modes. The factory default setting is RAID 5. If RAID
5 is your desired mode, then you can jump to the next section of the manual since no further configuration is required.
WARNING: Changing RAID mode will delete all data on the drive. Do not press the RAID Setup button to
change RAID mode unless you have first saved all of the data from the drive to another storage location.

RAID 0

RAID 0 (also called Striping) distributes data across both disks in a way which can improve throughput, while retaining
full capacity. However, in case of possible failure of any disk, all data will be lost and the array will no longer mount to
your computer. Available capacity is the combined capacity of all four drive cartridges.
If any disk fails in RAID 0 then the LED of the failed drive will change to RED.

RAID 1+0 (RAID 10)

Commonly referred to as RAID 10, RAID 1+0 (striping of mirror pairs) provides fault tolerance and improved perfor-
mance. This mode creates a striped set from two sets of mirrored drives. If a disk fails all the remaining disks continue to
be used. The array can sustain multiple drive losses so long as neither mirrored pair loses both of its drives.
Available capacity is equal to that of only two of the four included cartridges.
If a disk cartridge fails, then the LED corresponding to the failed disk will change to RED.

RAID 5

RAID 5 (Striping with distributed parity) combines four disks in a way that protects data against loss of any one disk. The
storage capacity of the array is reduced by one disk.

RAID Setting Steps

To change RAID mode, follow these steps:
1. If you have any important data stored on the drive, first save the data to another storage location.
2. While power is ON, use a pointed tool or pen point to depress and hold the RAID Setup button for at least 3 seconds.
3. Note the color of the front panel status LED. Press the front panel Function Button one or more times to
cycle to the LED color corresponding to the desired RAID mode:
Blue = RAID 0
Purple = RAID 1+0
White = RAID 5
4. Again, depress and hold the RAID Setup button for at least 3 seconds. The cartridge LEDs will begin flashing
blue to indicate that the array is being rebuilt to the new RAID mode. When flashing turns to solid blue the drive
has successfully reconfigured, though remains uninitialized, unpartitioned and unformatted.
5. You must now initialize, partition and format the drive array. Attach the drive to your host computer using
either USB, eSATA or FireWire. Your computer may show it as an unknown device, which confirms that the
drive remains uninitialized, un-partitioned and unformatted.
6. Partition and format the drive using the appropriate tools:
• For NTFS, use Windows tools (right-click on My Computer and select Manage / Storage / Disk Management).
• For HFS+, use Mac OS tools (Disk Utility). Note: For Intel-based Macs select GUID Partition Table for array sizes
larger that 750GB.
• For FAT32, use the FAT32 formatting utility supplied on the included CD-ROM.
You can find more information on formatting from the support web site listed under Getting Help.
7. When formatting is complete, confirm that the drive has mounted properly and a new drive icon appears in
My Computer (Windows) or a new icon appears on the desktop (Mac).
