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 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.
