Without /c2, it reads until the end.
Yes but I meant an option to continue dumping later...
1. The disc has many C2 errors and it needs 10000 or more retries to dump the sector. Imagine that we have many of these sectors. It's not the best way to leave the drive work several days. Also, cold drive reads better! More chances with cold drive!
2. This option would be also great... If no amount of retries was set. The disc was dumped but we need to re-read C2 sectors. Maybe it's possible to code an option to allow the DIC to go to the next sector if all 4000 attempts weren't successful? 4000 with next sector etc. And to go back to these previous sectors to try 4000 attempts again and again.
With the second option we can get as many sectors as possible to go back to really hard sectors.
The best way is to combine both options to allow to read hard sectors after the drive became cold again.
Something similar does IsoBuster. Program creates IBP/IBQ files with zero sectors (bad sectors), then with different drives or after cleaning disc you can fills zero(bad) sectors.
