Western Digital My Book Premium 500GB USB/FW 400 Ext Hard Drive
MyBook 500 GB is excellent
The unit works as advertised. <br /> <br />I did need to do a re-format to create both NTFS and FAT partitions. With the FAT32 partitions the unit also works with my iMAC as well with Windows. The backup to the MyBook is about as fast as USB can go. Once the files are on the MyBook, it is easy to copy the files off to my HP Storageworks DAT72 USB tape drive for long term saving.
