DARES(1)DARES(1)NAME
dares - rescue files from damaged CDs and DVDs
SYNOPSIS
dares -i image -s path [-h2i h2i_file] [-a] [-m] [-llogfile]
dares-qt [-i image] [-s path] [-h2i h2i_file] [-a] [-m] [-llogfile]
DESCRIPTION
Dares scans a CD/DVD image or a CD/DVD and tries to find files. It does not depend on filesystem information, but instead uses the Magic
library to identify files. Doing it this way Dares can recover files even when the filesystem (ISO-9660 or UDF) on the disc is damaged and
cannot be mounted anymore.
Dares can use H2cdimage (ftp://ftp.heise.de/pub/ct/ctsi/h2cdimage.zip) files to rescue data from heavily damaged optical discs.
OPTIONS -i CD/DVD image file or device.
-s Directory where the rescued files shall be stored.
-h2i Optional h2i file for the CD/DVD image.
-a Store all found files without any user interaction.
-m Use Mime types instead of a description. -l Logfile (default: dares.log)

MOUNT_UDF(8) BSD System Manager's Manual MOUNT_UDF(8)NAME
mount_udf -- mount an UDF file system
SYNOPSIS
mount_udf [-c] [-g gid] [-o options] [-t gmtoff] [-s session] [-u uid] special node
DESCRIPTION
The mount_udf command attaches the UDF file system residing on the specified special device node on the location indicated with node.
Anonymous files stored on the UDF disc will be represented and saved in the specified uid:gid pair. If unspecified, it will default to
nobody:nobody. Both uid and gid can be either specified with their names as with their numerical equivalents.
-c Close the session after unmount creating remountable snapshots. Closing a session also allows -ROM devices to read the disc cre-
ated. Note that this option only makes sense when mounting sequential recordable media like CD-R and DVD*R.
-g gid Set the group of anonymous files on the file system. The default group is the nobody group.
-o options Use the specified mount options as specified in mount(8).
-s session Select the session session to be mounted instead of the default last one. Implements readonly snapshots on sequential media.
Positive session values indicate an absolute session number. Negative session values are relative to the last session found on
the disc. Note that this option only makes sense when mounting sequential recordable media like CD-R and DVD*R.
-t gmtoff Set the time zone offset (in seconds) from UTC to gmtoff, with positive values indicating east of the Prime Meridian. If not
set, the user's current time zone will be used.
-u uid Set the owner of anonymous files on the file system. The default owner is the user nobody.

UDF is a file system defined by the OSTA standardization group and is tailored for data interchange on optical discs (like CDs and DVDs)
between different operating systems. Its also more and more common on other media like Compact Flash (CF) cards.
Read and write access is supported for all media types that CD/DVD type drives can recognise including DVD-RAM. BluRay support is prelimi-
nary; read-only access should work fine but write support is experimental.
Implemented and tested media types are CD-ROM, CD-R, CD-RW, CD-MRW, DVD-ROM, DVD*R, DVD*RW, DVD+MRW, DVD-RAM but the same code can also read
HD-DVD and BluRay discs. Discs created and written by UDFclient, Nero's InCD, and Roxio's DirectCD/Drag2Disc can be read without problems.
Both open and closed media are supported so there is no need to close discs or sessions.
All current UDF versions up to version 2.60 are supported.
Hard disk partitions and vnd(4) devices may also be mounted. Note when mounting a vnd(4) device it might be necessary to specify the file
image sector size in the geomspec when creating the vnd(4) device or the disc sector size will be used.
BUGS
Write support for UDF version 2.50 is not completely mature and UDF version 2.01 should be used if possible; this is also the default format.
Due to lack of test media and recording devices, BluRay support and in particular BluRay-R is still preliminary as of writing.
