Re: [Bug-ddrescue] Best options for rescuing a DVD?

[Burkart Lingner]

Hi Ian!

> Any other ideas?

Personally I would use ddrescuelog to generate a list of bad sectors and 
then see if from some point on ddrescue was unable to read any more 
data. If that's the case, readjust the rescue domain to a point before 
that. Maybe that's where the written data ends and in any case it would 
allow you to concentrate first on reading areas that can be read faster.

Have you tried mounting mem1.iso (or a copy thereof) as a loop device? 
Depending on how corrupted the image is and which areas are affected, 
this might give you an indication of how much data is stored on the disc.

Finally, when it comes to optical media I would try different 
drives/computers.

Good luck!
