For DVD+RW this is the only supported explicit formatting type. It provides
complete "de-icing" so no reader slips on unwritten data areas.
.TP
format_defectmgt
Format DVD-RAM to reserve a generous amount of spare blocks for defect
management.
.br
The following format_defectmgt_* allow to submit user wishes which
nevertheless have to match one of the available formats. These formats are
offered by the drive after examining the media.
.TP
format_defectmgt_max
Format DVD-RAM to reserve a maximum number of spare blocks.
.TP
format_defectmgt_min
Format DVD-RAM to reserve a minimum number of spare blocks. It might be
necessary to format format_defectmgt_none first in order to get
offered the most minmal spare blocks sizes for format_defectmgt_min.
.TP
format_defectmgt_none
Format DVD-RAM to the largest available payload in the hope to disable
defect management at all. This seems not to have a speed increasing effect,
though.
.TP
format_defectmgt_payload_<size>
The text after "format_defectmgt_payload_" gives a number of bytes, eventually
with suffixes "s", "k", "m". The largest number of spare blocks will be chosen
which allows at least the given payload size.
.TP
deformat_sequential
Like blank=all but with the additional ability to blank overwriteable DVD-RW.
This will destroy their formatting and make them sequentially recordable.
