       recoverdm - recover files on disks with damaged sectors


       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]


       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.


       -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

       -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
           CDROM_IDE       20
           CDROM_SCSI      21
           DVD_IDE         30
           DVD_SCSI        31
           DISK_IDE        40
           DISK_SCSI       41
