computer and try the format again. You may also come across this
error if you try to format the Drive using the FAT32 file 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?
A: You will get this alert message if you plugged the Drive into
a USB port that only support USB 1.1. This is fine, except your
Toshiba Drive will operate USB 1.1 speeds (up to 12 Mbps).
The Drive seems to be operating slower than 480 Mbps.
A: First, in order to reach USB 2.0 speeds, you need a connection
that supports USB 2.0. If the connection only supports USB 1.1 the
Drive will operate at USB 1.1 speeds (up to 12 Mbps). The Drive
will auto-sense the speed of your USB port and adjust between
USB 1.1 and USB 2.0. Second, 480 Mbps is the maximum speed of
USB 2.0 devices. Actual data transfer rates will vary depending on
a number of factors, including available CPU resources.
