The Always Thaw External Hard Drives pane has two checkboxes,
USB and
IEEE 1394 (FireWire) and both checkboxes are selected by default. This ensures that the USB or IEEE 1394 (FireWire) hard drives are always Thawed.
The USB and
IEEE 1394 (FireWire) checkboxes are selected in the
Always Thaw External Hard Drives pane, the external hard drives would be
Thawed.
The USB checkbox is selected. The IEEE 1394 (FireWire) checkbox is cleared. In this example, the
USB drive (
D:) would be Thawed and the
IEEE 1394 (FireWire) drive (
F:) would be Frozen.
