*The FAT32 file system has a maximum individual file size of 4 GB and cannot create partitions larger
than 32 GB in Windows. To create partitions larger than 32 GB in FAT32 when reformatting the drive,
download the External USB/FireWire FAT32 Formatting Utility from http://support.wdc.com/
downloads.aspx?p=34 . Windows users can avoid these size limitations by formatting the drive to
exFAT.

Frequently Asked Questions
Why is the drive not recognized under My
Computer or on the computer desktop?
If your system has a USB 3.0 or USB 2.0 PCI
adapter card, be sure that its drivers are installed
before connecting your WD USB 3.0 external
storage product. The drive is not recognized
correctly unless USB 3.0 or USB 2.0 root hub and
host controller drivers are installed. Contact the
adapter card manufacturer for installation
procedures.
