Does anybody have experience from repairing scratched cd:s? There are a few repair-kits available, but are they really doing their job? The cd:s I would be happy to play/copy are not very badly scratched, but some scratches are deep enough to make EAC (with accurate stream/c2) lose the sync.

sorry, I don't want to hijack this thread and I know that this is slightly offtopic:

I am trying to test if PAR2 recovery blocks really work in the way I am intending to use them, so this is what I did:

1. Burned a data CD
2. Extracted an ISO image with isobuster
3. Created par2 recovery blocks for the iso image
4. Marked the CD in the media side with a felt tip marker to make some of the sectors unreadable

My intention is to extract again an ISO image of this now "damaged" data CD and use the PAR2 recovery blocks to try to restore the original ISO image. However I am facing a problem because isobuster is taking ages to rip the image, even using only one reread per damaged sector. This is really making me reconsider using this strategy, because I feel that all the hassle is not worth the trouble. I am starting to think that in my case it would be better to just get the corrupt data from another source (for instance burn the original data in CD and DVD and if one gets corrupt use the other as source. If both get corrupt then it's a sign of God tongue.gif)...

The question is: is there another tool that would perform the ISO image rip in a faster way (something like burst mode in EAC)? Attempts of error correction at extraction would not matter much because I know that the data is already corrupted. It would be interesting that the tool also be able to rip data DVD images.

thanks for the help.
