mmcformat utility formats optical media conforming
to the MMC standard. This includes CD, DVD, and Blu-Ray (BD) media.
The options are as follows:
-B-b
blockingnr-c
cert-num-D-F-G-H-h-I-M-O-p-R-r-S-s-wmmcformat is made as generic as possible. This can
result in confusion.
mmcformat -B -O
/dev/rcd0dBlanks and then formats a CD-RW disc using the “old
style” format command. It is recommended to use this “old
style” command unless your drive reports that it's not supported; in
that case, resort to the default -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.
mmcformat -F -M
/dev/rcd0dFormat 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.
mmcformat command first appeared in
NetBSD 5.0.
mmcformat could be merged with
scsictl(8) but that tool is
very hard disk oriented.
