DESCRIPTION

The Digital Versatile Disk File System enables the reading of disks formated in the Universal Disk Format (UDF).

User data sectors in a DVD-ROM can contain any type of data in any format. However, for DIGITAL UNIX support through the dvdfs file system, the OSTA UDF file format standard is mandatory.

Additionally, DVD-ROM standards require that the logical sector size and the logical block (the user data block) size be 2048 bytes.

DVD support in the UDF specification includes these levels: DVD-ROM (Read-only):

Supports reading of UDF-formated files from DVD-ROM disks. DVD-R (Write-once):
Supports the reading of UDF-formated files from a DVD-ROM disk and supports writing, one time, UDF-formated files onto a DVD-ROM disk. DVD-RAM (Rewritable):
Supports reading and writing of UDF-formated files from and to a DVD-ROM disk.

At this time, the DIGITAL UNIX dvdfs file system supports only the DVD-ROM (Read-only) format.

See mount(8) for information about mounting and unmounting a dvdfs file system, fstab(4) for information about including dvdfs file system in a system's /etc/fstab file, and disklabel(8) for information about labeling DVD-ROM disks.
