Are you still challenging to dump this disc?

No, it's another disc. No big scratches but some C2. I would try more and more because several sectors were done after 10000-15000 retries so I still have a hope. Cold drive and disc also work better sometimes.

Now it leaves empty sectors after hard sectors which can be done after several retries. A continue option would help to dump at least these readable sectors after hard or very hard sectors.

Some sectors in your CD-R perhaps can't recover, so resume function is also vain efforts I think. Please get new CD-Rs if it's possible.

No way to get any new ones. They are the only known.

The first one mentioned above is scratched. I still need to resurface it to try again. The second one is not scratched but some sectors are very hard to dump. Maybe even impossible but it's hard to say without continue option. The discs are press/preview discs.

I would try more and more but the only way now is to set millions attempts and to leave the drive to work several days. No way to try with cold drive and disc then.

Just a couple of old CD-Rs.

How to continue dumping using the same files? Since I set more than 10000 retries, image files were created but I still need to dump next hard sectors. Tried the same command but it just overwrites existing files. Which command should I use to continue? I use command line.

Would be very nice if DIC would try to read next hard sector if previous one wasn't dumped after all retries. It would help to dump all hard sectors leaving only very hard ones. Is it possible to add this function?

With new version the disc just stops after about one minute but no more messages.

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.

I have worry about spreading the c2 existing image.

Logs will tell about it anyway. Also, it's not a problem to modify any existing ISO or file to fake.

This option would be extremely helpful for dumping old hard CD-Rs.

Just put 10000 after /c2.

Thanks!

I have an idea... I recently got a disc and it's old CD-R. DIC shows hundreds of C2 errors so it requires lots and lots of retries. I now set up 100000 retries but dumping process already took about three hours. I think I might need several days with lots and lots of retries but it's not a good idea to keep the drive working several days. Already done a couple of sectors after 20000 retries...

Maybe it's possible to code an option to let you continue dumping process? Something like DIC checks log file and the dump and starts more retries if dumping process wasn't done.

Since I already done a couple of very hard sectors, it's not a good idea to stop dumping process but maybe even 100000 retries won't be enough...

Quick question... How to add more retries? 4000 is not enough. I want to try 10000 or more.

Why it creates more sectors than the disc has? The disc is copy protected somehow by the last 15900 sectors. It's old review CD-R.
