NAME
recoverdm - recover files on disks with damaged sectors
SYNOPSIS
recoverdm -t <type> -i <file/device-in> -o <output_file> [-l <sectors_file>] [-n retries]
[-s rotation_speed] [-r retries] [-b start_offset] [-p skip_blocks_count]
DESCRIPTION
recoverdm recover disks with bad sectors. You can recover files as well complete devices. In case it
finds sectors which simply cannot be recovered, it writes an empty sector to the output file and
continues.
When recovering a CD or a DVD and the program cannot read the sector in "normal mode", then the program
will try to read the sector in "RAW mode" (without error checking etc.). This toolkit also has a utility
called mergebad which merges multiple images into one.
OPTIONS
-t <type>
See the above table to choose a value for <type>.
-i <file/device-in>
Device or file to recover.
-o <output_file>
File where to write to. This file should not already exist.
-l <sectors_file>
Generates a mapfile containing checksums and a list of bad sectors. This mapfile can then be used
with mergebad to create one correct image from several damaged images.
-n retries
Number of retries before going on with next sector. Default is 6. For CDROMs it is advised to use
1.
-s rotation_speed
Rotation speed of CDROM/DVD. Default is 1.
-r retries
Number of retries while reading in RAW mode before going on with next sector. Default is 6. It is
advised to use at least 3.
-b start_offset
Point to start.
-p skip_blocks_count
How many sectors are skipped after non-read one. Use more to speed-up the recover process. Default
is 1.

These are the values can be used with -t option:
FILE 1
FLOPPY 10
FLOPPY_IDE 11
FLOPPY_SCSI 12
