.Sh NOTES
|
|
Due to the enormous varieties in optical media,
|
|
.Nm
|
|
is made as generic as possible.
|
|
This can result in confusion.
|
|
.Sh EXAMPLES
|
|
.Dl Ic mmcformat -B -O /dev/rcd0d
|
|
.Pp
|
|
Blanks and then formats a CD-RW disc using the
|
|
.Dq old style
|
|
format command.
|
|
It is recommended to use this
|
|
.Dq old style
|
|
command unless your drive reports that it's not supported; in that case, resort
|
|
to the default
|
|
.Fl F .
|
|
Note that a CD-RW disc can be reformatted without being blanked.
|
|
Blanking switches between sequential and fixed packet writing by
|
|
erasing the disc.
|
|
This can also help to revive old discs.
|
|
.Pp
|
|
.Dl Ic mmcformat -F -M /dev/rcd0d
|
|
.Pp
|
|
Format a CD-RW or a DVD+RW to use MRW (Mount Rainier).
|
|
This format tries to hide media flaws as much as possible by
|
|
relocation.
