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 may attempt 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.
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 2.0 adapter card or a system that does not support USB 2.0.
Q: How do I determine whether or not my system supports USB 2.0?
A: Refer to your USB card documentation or contact your USB card manufacturer.
Note: If your USB 2.0 controller is built into 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 2.0 device is plugged into a USB 1.1 port or hub?
A: USB 2.0 is backward-compatible with USB 1.1. When connected to a USB 1.1 port
or hub, a USB 2.0 device operates at the USB 1.1 full speed of up to 12 Mb/s.
If your system includes a PCI slot, you can achieve Hi-Speed USB transfer rates by
installing a USB 2.0 PCI adapter card. Contact the card manufacturer for installation
procedures and more information.
