FAT file system. If reformatting the Drive and you do not need Mac

compatibility, Windows Vista/XP/000 users should use the NTFS files

system.

After I connected the Drive to my PC, I got the following alert

message: “Hi-Speed USB device plugged into non-Hi-Speed USB

Hub.” What does this mean?

Windows Vista, XP and 000 users will get this alert message if you

plugged the Drive into a USB port that only supports USB 1.1. This is

fine, except your Drive will operate USB 1.1 speeds (up to 1 Mbps).

Performance via USB seems to be slower than 480 Mbps.

First, in order to reach USB .0 speeds, you need a connection that sup-

ports USB .0. If the connection only supports USB 1.1 the Drive will

operate at USB 1.1 speeds (up to 1 Mbps). The Drive will auto-sense

the speed of your USB port and adjust between USB 1.1 and USB .0.
Second, 0 Mbps is the

maximum

speed of USB .0 devices. Actual

data transfer rates will vary depending on a number of factors, includ-
ing available CPU resources.
