Frequently Asked Questions

Q: Why does the drive not power up or is not recognized by the computer?
A: You must use the FireWire or USB cable supplied in the kit. For USB connectivity, a special USB cable may
be needed for computers with limited bus power. For more information in the U.S., visit shopwd.com. Outside
the U.S., contact WD Technical Support in your region. If your system has a USB2.0 PCI adapter card, be
sure that its drivers are installed before connecting your WD USB 2.0 external storage product. The drive is
not recognized correctly unless USB 2.0 root hub and host controller drivers are installed. Contact the
adapter card manufacturer for installation procedures.
Q: How do I partition and reformat the drive for Windows?
A: For directions on how to partition and format this device for Windows, please search our knowledge base for
answer ID 1550 at support.wdc.com.
Q: Why is the data transfer rate slow?
A: Your system may be operating at USB1.1 speeds due to an incorrect driver installation of the USB 2.0
adapter card or a system that does not support USB 2.0. 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.
