recoverdm

RECOVERDM(1)						      General Commands Manual						      RECOVERDM(1)

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.

OPTIONS

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

       -i filedevicein
	      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-ROMDVD, defaults to 1.

       -h     Gives the help message.
