Question about unrecoverable skipped sectors

[gcoimbra]

Hello! I have a question about dvdisaster behaviour in the presence of unrecoverable/ skipped errors.

Let's suppose the data in disc is as follows:

Data Legend: O -> Ok B -> Bad (skipped / unrecoverable)

    ID: 0 1 2 3 4
Data: O O B B O

Does dvdisaster will recover that the following way:

  ID: 0 1 2 3 4
Data: O O B B O

respecting the original structure of the data.

Or will it won't write bad sectors, having the data this way:

    ID: 0 1  4
Data: O O O

I ask this because I need data to be exactly aligned as I written them to use par2 correctly and recover that data. I wasn't aware of dvdisaster tool at the time and used par2 on this data.

When recovering, dvdisaster will always respect the data alignment, i.e. you'll always end up with an image the same size than the original one. So in your case, the par2 files will work as long as the filesystem structure on the disc is not damaged (i.e. files can be listed and located properly on the disc).

It indeed worked, thanks a lot, this software saved my life!
