**This WD drive is preformatted as a single FAT32 partition for compatibility with all Mac and Windows operating systems. The FAT32 file

system has a maximum individual file size of 4 GB and cannot create partitions larger than 32 GB in Windows 2000/XP; however,
Windows 2000/XP users can overcome these file size limitations by reformatting the drive to NTFS using the Disk Management utility.

Frequently Asked Questions — USB Information

Q: What is Hi-Speed USB?

Hi-Speed USB is another name for USB 2.0, which provides transfer rates up to 40 times faster than
USB 1.1. Upgrading to USB 2.0 is highly recommended because of the significant reduction in file transfer
time versus USB 1.1.

Q: How do I determine whether or not my system supports USB 2.0?

Refer to your USB card documentation or contact your USB card manufacturer.
Note: If your 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 2.0 device is plugged into a USB 1.1 port or hub?

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 Mbps.

Q: Can USB 1.1 cables be used with USB 2.0 devices?

Although USB 1.1 cables work with USB 2.0 devices, it is recommended that USB 2.0 certified cables be
used with USB 2.0 peripherals and USB 2.0 PCI adapter cards.

Frequently Asked Questions — Installation

Q: Why does the drive not power up?

Be sure the drive is plugged in to a power source.

Q: Why is the drive not recognized under My Computer or on the computer desktop?

If your system has a USB 2.0 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?

Q: 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 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.
