Before you connect the Drive, please carefully read the notes and
restrictions below. Failure to adhere to any of them can damage
the Drive and void the warranty:
If your 550 Drive came with two power cords, be sure to use the•
correct cord for your region.
Do not use more than one interface cable to connect the Drive to•
your computer.
Do not connect the Drive to more than one computer at a time.•
If your Drive is equipped with FireWire, you can daisy-chain•
another FireWire device to the Drive. See "Daisy-Chaining the
Drive".
Do not connect a USB device to the Drive. USB devices must be•
connected to the computer, either directly or via a USB hub.
Interface cable connectors can only be plugged•
in one way. Be sure to orient them correctly when
you insert them.
The USB cable has a type A connector and a type•
B connector. The type A connector plugs into a
USB port on your computer or hub; the type B
connector plugs into the Drive.

Step 1: Connect the AC adapter and power cord:
1a) Plug the AC adapter into the Drive's Power Port.
The AC adapter connector can be inserted into
the Drive’s Power Port only one way. It should not
require much effort to plug in. If the connector will
not go in, check the orientation and try again. Do
not force the connector or you may damage it
and/or the Drive and void the warranty.
1b) Plug the power cord into the socket in the AC
adapter. Plug the other end into an AC outlet.
Step 2: Connect the interface cable:
2a) Select the interface cable you wish to use and plug one end into a
corresponding port on your computer/hub.
2b) Plug the other end into the correct port on the back of the Drive.
Step 3: Flip the Drive's Power Switch to turn it on:
When the Drive mounts to your operating system, it's ready to use…
Windows users will see a new drive icon/letter in My Computer.
Mac users will see a new icon on the Desktop and in the Finder.

Never turn off a hard drive or disconnect any cables while it is mounted to a
computer's operating system. You may lose data or damage the drive.
Windows users
1. In the Windows Taskbar click the Safely Remove icon (the icon
with the green arrow). A pop-up message will appear with a list of
devices connected to your computer.
2. Select the Drive from the list. After a few seconds Windows will
display a message indicating it is safe to remove the device.
3. Click OK. You can then safely turn off the Drive.
Mac users
Drag the Drive's icon to the Trash. After the icon disappears from the
Desktop you can safely turn off and/or disconnect the Drive.
Whether you are using a Mac or a PC…
If you turn off the Drive after you shut down your computer, you do not need to
unmount it. The Drive will unmount automatically during shutdown.

Daisy-chaining the Drive
A daisy-chain is a grouping of devices linked one after another
in series, starting from the computer (as shown in the illustration
below). If your Drive is equipped with FireWire, you can daisy-
chain another FireWire device to it. See the next page for more
information.

What you need to know about daisy-chaining:
You cannot daisy-chain USB devices. Do not connect a USB•
device to the Drive.
FireWire ports can be used in any order. For example, it does not•
matter which port you use to connect the Drive to your computer
and which port you use to connect another FireWire device.
You can locate the Drive anywhere in a daisy-chain (e.g. first, last,•
or somewhere in the middle).
Data transfer rates between two devices in a daisy-chain will•
be limited by the device with the slower interface. For example,
data transfers between a FireWire 400 hard drive and a FireWire
800 hard drive will be limited to FireWire 400 speeds.
FireWire devices with only one FireWire (1394) port (e.g. digital•
camcorders) will necessarily be placed last in a daisy-chain.
Bus-powered devices, such as 2.5" portable hard drives, can be•
included in a daisy-chain, provided the Drive's FireWire port sup-
plies sufficient power to run the device.
