NAME

recovermov - recover movies from a filesystem image

SYNOPSIS

recovermov [options] device

DESCRIPTION

Recovermov tries to identify mov movies from a filesystem image. To achieve this goal, it scans the filesystem image and looks for a mov structure at blocks starting at 512 bytes boundaries.

recovermov stores the recovered movies into the current directory. If you want it to store them elsewhere, just go to the directory you want recovermov to save the movies into (using the cd command at the shell prompt) and start recovermov from there, or use the -o option.

Note that device is not necessarily a physical device. It may also be a file containing a copy of the faulty device in order to reduce the actual processing time and the stress imposed to an already defective hardware. dd(1) or ddrescue(1) may be used to create such a working copy.

OPTIONS

-h

Display an help message.

-b blocksize

Set the size of blocks in bytes. On most file systems, setting it to 512 (the default) will work fine as any large file will be stored on 512 bytes boundaries. Setting it to 1 maximize the chances of finding very small files if the filesystems aggregates them (UFS for example) at the expense of a much longer running time.

-i integerindex

Set the initial index value for image numbering (default: 0).

-n basename

Basename to use to create the salvaged files. Default is video_.

-o directory

Change the working directory before restoring files. Use this option to restore files into a directory with enough space instead of the current directory. This option can be repeated.

-V

Display program version and exit.

All the sizes may be suffixed by a k, m, g, or t letter to indicate KiB, MiB, GiB, or TiB. For example, 6m correspond to 6 MiB (6291456 bytes).

EXAMPLES

Recover as many movies as possible from the memory card located in /dev/sdc:

recovermov /dev/sdc
    

Recover as many movies as possible from a crashed ReiserFS file system (which does not necessarily store files at block boundaries) in /dev/hdb1:

recovermov -b 1 /dev/hdb1
