Packages and Binaries:
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.

Block bitmap statistics for myrescue
[email protected]:~# man myrescue-stat myrescue-stat(2) System Calls Manual myrescue-stat(2) 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.
