Why won't my computer boot when I connect
my USB drive to the computer before booting?
Depending on your system configuration, your
computer might try to boot from your WD
portable USB drive. Refer to your system’s
motherboard BIOS setting documentation to
disable this feature or visit
http://support.wdc.com and see Knowledge
Base answer ID 1201. For more information about
booting from external drives, refer to your system
documentation or contact your system
manufacturer.
Why is the data transfer rate slow? Your system may be operating at USB 1.1 speeds
due to an incorrect driver installation of the
USB 3.0 or USB 2.0 adapter card or a system that
does not support USB 3.0 or USB 2.0.
How do I determine whether or not my system
supports USB 3.0 or USB 2.0?
Refer to your USB card documentation or contact
your USB card manufacturer.
Note: If your USB 3.0 or USB 2.0 controller is
built in to the system motherboard, be
sure to install the appropriate chipset
support for your motherboard. Refer to
your motherboard or system manual for
more information.
What happens when a USB 3.0 or USB 2.0 device
is plugged into a USB 1.1 port or hub?
USB 3.0 and USB 2.0 are backward-compatible
with USB 1.1. When connected to a USB 1.1 port
or hub, a USB 3.0 or USB 2.0 device operates at
the USB 1.1 full speed of up to 12 Mbps.
If your system includes a PCI Express slot, you
can achieve USB transfer rates by installing a PCI
Express adapter card. Contact the card
manufacturer for installation procedures and
more information.
