Good day, I was wondering how I can get ddrescue to revisit previously skipped areas? I was using the following commands to copy as much data from undamaged/minimally damaged areas while getting it to skip ahead when encountering slow reading areas (I assume these are the damages areas).
sudo ddrescue --direct --sparse -a 20000 -K 100000 -i 0 -T 1 /dev/sdc /mnt/wd/image /mnt/wd/log I've tried using the following command, and I understand it will revisit all areas starting from 0 bytes. sudo ddrescue --direct --sparse -A --retrim -a 20000 -K 100000 -i 0 -T 1 /dev/sdc /mnt/wd/image /mnt/wd/log Previously when I tried using both the -i (`--input-position=bytes') and -s (`--max-size=bytes'), I seem to be encoutering some errors as my 500 GB faulty hard disk produced a partially copied image of 544 GB (I stopped the process when I saw the image size). Can you guys kindly enlighten me on how I can use the -i and -s command properly? Many thanks!
