Hello I'm doing an image of an ntfs disk with the GNU utility ddrescue, I made a first pass with the -n option which resulted in an amount of non-scrapped data, a bad-sector amount, a number of bad-areas and a number roughly equal to the previous of read-errors.
Following this, I re-launched the command with the log file with the option -r1 which brought the amount of non-scrapped to 0B and as expected increased the amount of bad-sector and lowered the number of bad-areas (~ divided by 2), this also increased the number of read-errors by a factor of 6 !
I would like to know what to do now, I guess I will have to restart the command with -r3 (or more)? What if there is still unrecovered data, continue or give up at this point? Can the -M and/or -d options help? (What about the -I -J -O options?)
n.b: the first passes did not suffer from any problem of speed or latency.
