myrescue

myrescue is a program to rescue the still-readable data from a damaged harddisk, CD-ROM, DVD, flash drives, etc. It is similar in purpose to dd_rescue (or ddrescue), but it tries to quickly get out of damaged areas to first handle the not yet damaged part of the disk and return later.

This package is useful to recover data from any media and for forensics investigations.

NAME
       myrescue-stat - Block bitmap statistics for myrescue

SYNOPSIS
       myrescue-stat bitmap-file

DESCRIPTION
       myrescue-stat reads a block bitmap from myrescue(1) and prints the num-
       ber and percentage of blocks for the different conditions.

       Possible conditions are:

       0 = Block has not yet been handled.

       1 = Block was successfully copied.

       2 = Block was successfully copied, but took a long time to read.
              (This usually indicates that the block is almost dead.)

       Negative values = Attempts to read the block have so far failed.
              The absolute value indicate the number of failed read attempts.
