speeds, as reported by the drive. They would be chosen by
|
||||
-read_speed "min" or "max" if they undercut or surpass the built-in
|
||||
limits. These are "1x", "52xCD", "24xDVD", "20xBD".

||||
both, respectively. The currently recognized type is marked by

text "(current)".
|
||||
-truncate_overwritable entity id adjust
|
||||
On overwritable medium copy the volume descriptors of an existing
|
||||
session to the overall descriptors at LBA 0 ff. This makes all
|
||||
sessions *inaccessible* which are younger than the activated one.
|
||||
A reason to do this would be read errors in the younger sessions
|
||||
and the wish to re-write or skip them.
|
||||
This operation is only allowed if no changes to the loaded
|
||||
filesystem are pending. If an -indev is acquired then it is
|
||||
released before the write operation begins and re-acquired only in
|
||||
case of success.
|
||||
The parameters "entity" and "id" have the same meaning as with
|
||||
command -load. They choose the existing ISO session which shall
|
||||
become the youngest accessible session. Available entity names are
|
||||
"session", "track", "lba", "sbsector", "volid". "auto" makes few
|
||||
sense. id is a number or search text as appropriate for the given
|
||||
entity.
|
||||
Parameter "adjust" controls the claimed size of the activated
|
||||
session. Text "new" means the size of the newly activated session
|
||||
as it was before this command. I.e. the space of the then
|
||||
inaccessible younger sessions will be re-used when appending more
|
||||
sessions.
|
||||
"old" means the size up to the end of the previously youngest
|
||||
session. I.e. "old" will not free the space of the then
|
||||
inaccessible younger sessions for re-use.
|
||||
A number preceded by "+" gives the number of bytes to be added to
|
||||
"new". A number without "+" gives the overall number of bytes. In
|
||||
any case the result may not be smaller than "new". Numbers may
|
||||
have a unit suffix: "d"=512, "k"=1024, "s"=2048, "m"=1024k,
|
||||
"g"=1024m.
|
||||
Examples:
|
||||
Activate session 4 and enable overwriting of the blocks of younger
|
||||
sessions:
|
||||
-truncate_overwritable session 4 new
|
||||
Activate session 4 and claim the blocks of younger sessions as
|
||||
useless part of session 4:
|
||||
-truncate_overwritable session 4 old
|
||||
Let session 4 claim additional 500 MiB as useless data:
|
||||
-truncate_overwritable session 4 +500m

||||
