NAME
recoverdm - recover filesdisks with damaged sectors
SYNOPSIS
recoverdm -t type -i filedevicein -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 sec-
tors 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)

-l list

image with the mergebad utility.
