Packages and Binaries:

recoverdm

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

mergebad

Merge multiple images into one

root@kali:~# mergebad -h
-i <mapfile> <imagefile>
		With -i one selects a mapfile+imagefile to read.
-o <outputfile>
		File to write output to.
-l <mapfile>	In case all inputimages had a badblock on the same
		place, this file will list those blocks.
-s <size>	Limit or extend the size of the outputimage.
-v		Be verbose.
-h		This help.

recoverdm

Recover files on disks with damaged sectors

root@kali:~# 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
