The SES (SCSI Enclosure Services) driver is different from the Virtual CD,
and the WD SmartWare software. To access many of the optional features of your
drive, you will be required to install both the SES driver, and the WD SmartWare
software. If you wish to use the drive as a simple hard drive and do not require
access to the advanced features of the drive, you can hide the VCD by following

OSX on a My Book or My Passport drive . Western Digital still recommends
installing the SES driver when not using WD SmartWare, but the drive will
function without it. The prompts to install the driver are part of the Windows
Operating system and will always occur when connecting a drive to a Windows PC
without the driver installed.
You can download a copy of the SES driver from our knowledge base. For
assistance doing this please see Answer ID 5419: WD SES driver download and
instructions for recovering the WD SmartWare installer.
Windows attempts to install a driver called the SES Driver every time I
connect the drive to a computer. What is this driver, why is it required and how
can I get rid of the repeated prompts to install the driver?
Your new Western Digital My Passport/My Book hard drive requires a special
communications channel (SCSI) between your PC and the drive to enable certain
features such as password protection, LED control, and access to the drives
label if applicable.
At install, the Windows operating system detects this SCSI communications
channel and attempts to install a SCSI Enclosure Services (SES) driver. This
driver is only used by your hard drive and is installed by default when you
first attach the drive to a computer.
However if you did not install the driver upon first install and chose not to
install WD Smartware, Windows will continue to prompt you to install the driver
each time you connect the drive to a computer. This will continue to occur
unless the SES driver is installed.
We recommend that you install the driver by selecting the Install the
software automatically option on the popup screen. Windows will automatically
find the Windows SES driver online, and the prompting will disappear. This will
not affect your operating system negatively in any way. If Windows is unable to
find the driver you can download a copy of the driver from Answer ID 5419: WD
SES driver download and instructions for recovering the WD SmartWare installer.
