DriveStation Setup

Flip the power switch on the back of the DriveStation to the OFF position. Plug DriveStation’s power cord into the power socket as shown, as well as a power outlet or surge protector. Then, connect a USB or eSATA cable into a matching port on the back of the DriveStation.

Connect the USB or eSATA cable to your Mac or other device you are adding the DriveStation to.


DriveStation Setup

Flip the power switch on the back of the DriveStation to the ON (“I”) position.

Your Mac will detect the new drive and place an icon on your desktop.

Your DriveStation is now ready for use! Double-clickon the icon to open the hard drive.


Installing the RAID Utility

By default, your Quattro is configured in RAID 0 mode. This gives you maximum usable capacity and performance, but no redundancy. If a drive fails, all data on the DriveStation is lost. 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 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.

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.

To install the RAID utility, open the Mac folder on your DriveNavigator CD.

Double-clickonRaidSetting.dmg to install the RAID utility.


Using the RAID Utility

Double-clickthe RaidSetting icon on your desktop. Once launched, the RAID utility will briefly scan for your DriveStation Quattro. This may take a few seconds.

The initial screen will show your current configuration. If your Quattro is new, it will probably be in RAID 0 mode, with all four disks in one high-performancepartition.

To change the RAID mode, click RAID Settings and chooseChange Disk Structure.


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.


Drive Select

If your hard drives are in “Normal” (JBOD) mode, then the Drive Select button lets you choose which of the 4 separate drives will be seen as the primary drive by your PC.

If you are using a USB connection with JBOD mode, then you will still be able to see all four separate hard drives in My Computer. If you are using an eSATA interface to connect Quattro only one single drive will be active in this mode. Use the Drive Select button

to chose which drive will be active in this case.

If four separate drives are not desired, use RAID 0, RAID 1, or RAID 5 instead of “Normal” (JBOD) mode. You may switch between RAID modes with the RAID utility during installation. The utility may also be installed or run from your DriveNavigator CD.

If you’ve changed the Quattro’s RAID mode to normal (JBOD) mode with the RAID setting utility, disconnect the Quattro from the computer. Hold the Select button for three seconds or until the Power LED is lit orange and beeps. Click theSelect button again to change which single drive is activated. You can see which drive is selected by its Access LED.

Here’s what the LED colors mean: Green: Selected and activated.

Orange: Not selected but activated. If you are using a USB connection the drive will still be visable in My Computer. With an eSATA connection, only the selected drive will be usable.

Off: Not selected and invisible to your PC.

If you are in a RAID mode where the four drives appear as a single drive, such as RAID 0, 1, or 5, then the Drive Select button is disabled.

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.
