Packages and Binaries:
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.
This package is useful in forensics investigations.
How to install:
sudo apt install recoverdm

Recover files on disks with damaged sectors
[email protected]:~# recoverdm --help recoverdm: invalid option -- '-' Usage: recoverdm -t <type> -i <file/device-in> -o <fileout> [-l <sectorsfile>] [-n # retries] [-s rotation speed (CD-ROM etc.)] [-r # CD/DVD RAW read retries] [-b start offset] [-p skip blocks count] Number of retries defaults to 6. For CD-ROMs it's advised to use 1. Number of CD/DVD RAW read retries defaults to 6. It is advised to use at least 3. CD-ROM (and DVD) speed defaults to 1. Skip blocks count is how many sectors are skipped after non-read one. Use more to speed-up the recover process. Default is 1. Type can be: 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 -l generates a mapfile containing checksums and a list of badsectors. This map- file can then be used with `mergebad' to create one correct image from several damaged images
