Q:
Why won't my computer
boot when I connect my USB drive to the computer before
booting?
A:
Depending on your system configuration, your computer might try to boot from your
WD external USB drive. Refer to your system’s motherboard BIOS setting
documentation to disable this feature or visit
see
Knowledge Base answer ID 1201. For more information about booting from external
drives, refer to your system documentation or contact your system manufacturer.
Q:
Why is the data transfer rate slow?
A:
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.
Q:
How do I determine whether or not my system supports USB 3.0 or USB 2.0?
A:
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.
Q:
What happens when a USB 3.0 or USB 2.0 device is plugged into a USB 1.1 port or
hub?
A:
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.
