The Always Thaw External Hard Drives pane has two check boxes,
USB and
IEEE 1394 (FireWire) and both check boxes are selected by default. This ensures that the USB or IEEE 1394 (FireWire) hard drives are always Thawed.
Let us assume that E: corresponds to a USB hard drive and
F: corresponds to an IEEE 1394 (FireWire) hard drive.
The USB and
IEEE 1394 (FireWire) check boxes are selected in the
Always Thaw External Hard Drives pane, the external hard drives would be
Thawed.
The USB check box is selected. The IEEE 1394 (FireWire) check box is cleared. In this example, the
USB drive (
D:) would be Thawed and the
IEEE 1394 (FireWire) drive (
F:) would be Frozen.
