NAME

recoverdm - recover files/disks with damaged sectors

SYNOPSIS

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

DESCRIPTION

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.

-l list
