recoverdm -t type -i file\/devicein -o fileout [-l list] [-n retries] [-s speed]


recoverdm This program will help you recover disks with bad sectors. You can recover files as well complete devices. In case if finds sectors which simply cannot be recoverd, it writes an empty sector to the output file and continues. If you're 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': mergebad merges multiple images into one. This can be useful when you have, for example, multiple CD's with the same data which are all damaged. In such case, you can then first use recoverdm to retrieve the data from the damaged CD's into image-files and then combine them into one image with mergebad.


-t type

is 1 for files, 10 for floppy disks and 40 for IDE disks (try -h for a complete list)

-i file\/devicein

is the device or file you want to recover.

-o fileout

is the file where to write to. This file should not already exists.

-l list

This file will contain the offsets of the bad blocks as well as the size of the bad blocks. This file can be used together with the image with the mergebad utility.

-n retries

Number of retries before going on with next sector, defaults to 6.

-r RAW read

Number of retries while reading in RAW mode before going on with next sector, default to 6.

-s rotation speed

Speed of the CD-ROM\/DVD, defaults to 1.
