to the MMC standard. This includes CD, DVD, and Blu-Ray (BD) media.

- 0
- no certification
- 1
- full certification
- 2
- quick certification
-D- Debug mode. Print all SCSI/ATAPI command errors.
-F- Format media.
-G- Grow last CD-RW/DVD-RW session.
-H- Show help and print formatting choices for the inserted media.
-h- Show help and print formatting choices for the inserted media.
-I- Show help and print formatting choices for the inserted media.
-M- Select MRW (Mount Rainier) error correcting background format.
-O- Old style CD-RW formatting; recommended for CD-RW.
-p- Explicitly set packet format.
-R- Restart previously stopped MCD-MRW or DVD+RW background format.
-r- Recompile defect list for DVD-RAM.
-S- Grow spare space DVD-RAM / BD-RE.
-s- Format DVD+MRW / BD-RE with extra spare space.
-w- Wait until completion of background format.
NOTES¶
Due to the enormous varieties in optical media,mmc_format is made as generic as possible. This can
result in confusion.
EXAMPLES¶
mmc_format -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.
mmc_format -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.

mmc_format could be merged with
scsictl(8) but that tool is very hard disk oriented.
