2 : Not regular format, but can be read and written.
3 : Can not be read or written.

disk formatting. During formatting, a message to that effect, “Formatting
disk...” is displayed on the screen.
NOTE. A disk with its write prevent tab in the write-protected position cannot be

When formatting is complete, the message on the screen will disappear and
an empty file list will appear with the format type and available disk space
shown in the upper right-hand corner.
