Turning Off/Disconnecting the Drive
Auto-Off
My Book turns off automatically when you shut down the computer. You also may follow these steps to turn off
the drive.
Important: To prevent data loss, close all active windows and applications before shutting down the drive.
Safe Shutdown
™
The Power button features Safe Shutdown, which prevents the inadvertent powering down of the drive until all
data is written to the drive or system. To engage Safe Shutdown, press the Power button once. You may hear
the drive power down before the Power LED turns off. The drive is now shut down properly, and you may
disconnect the drive safely.
Safe Shutdown is enabled only through installation of its driver, which must be installed on each system to
which My Book is connected.
For Mac, you must install the Button Manager and driver (see "Installing the Drive" on page 3).
For Windows, the autorun menu appears only on first installation of the drive, during which utilities are installed
automatically. If AutoPlay is disabled on your computer or if you are connecting My Book to another computer,
you must install utilities manually. Go to the desktop. Double-click My Computer, the My Book folder, the
WD_Windows_Tools folder, and Setup.exe.
Safe Removal
Mac
Drag the My Book icon to the Trash icon for proper dismount. You may hear the drive power down as the
Power LED flashes. When the Power LED is steady, you may press the Power button once or disconnect the
drive's power cord to turn off the drive safely.
Windows
Right-click the Safely Remove Hardware icon
You may hear the drive power down before the Power LED turns off. The drive is now shut down properly, and
you may disconnect the drive safely.

maximum individual file size of 4 GB and cannot create partitions larger than 32 GB in Windows 2000/XP; however, Windows 2000/XP users can
