fsck_udfUniversal Disk Format file system consistency checker

fsck_udf -p [-fH] file system ...

fsck_udf [-fHnSsy] file system ...

The fsck_udf utility verifies and repairs Universal Disk Format file systems (more commonly known as UDF file systems).

The first form of fsck_udf preens the specified file systems. It is normally started by fsck(8) run from /etc/rc during automatic reboot, when an UDF file system is detected. When preening file systems, fsck_udf will fix common inconsistencies non-interactively. If more serious problems are found, fsck_udf does not try to fix them, indicates that it was not successful, and exits.

The second form of fsck_udf checks the specified file systems and tries to repair all detected inconsistencies, requesting confirmation before making any changes.

The options are as follows:

Force detailed checking even when file system is marked closed.
Enables heuristic repair options repairing known corruptions in the wild caused by bugs.
Causes fsck_udf to assume no as the answer to all operator questions.
Preen the specified file systems.
Causes fsck_udf to scan for older VAT tables on recordable media. This allows older snapshots of the file system on recordable media to be recovered.
session
Select session session to be checked on recordable media. This allows older sessions of the file system on recordable media to be recovered.
Causes fsck_udf to assume yes as the answer to all operator questions.
