Yes that might the only option for me.
I will have to buy the most expensive CDr-drive out there and try to make a good image with that one.
The disc is absolutely new, no scratches or physical damages in any way.
It was created in 1995/96 and put into a custom cd-case. A few other copies were made, too, but are now absolutely unreadable. This last copy is the only one that let’s me read out 68-70% of it’s content. The errors then get more and more often. From on 72% of the disc each sector seems damaged. Even a hundret retries on my LG 4040B drive won’t help to get the right info out of that sector.
So what to do? I got the info to try BlindWrite 4.2.5 which would allow me to create .iso images. Well, I tried converting my .b5i image to an .iso which resulted in an AudioCD. But I gave it a try and let BlindWrite 4 create another image from my ECD in .iso format. It worked. The result is not an AudioCD and everything runs as intentioned (except for the damaged files of course.) I have not tested those so-called editors for .iso images yet but maybe I am in luck and it will work for me. I have heard bad news about editing .iso images. Since I won’t touch the toc or anything else than the binary content of the files it might turn out well. I hope.
So this thread turns into:
(1) Is the content of files inside an .iso image written in sequence? Then my hex editor would do everything I need. (I can answer this question, too, when I am back home in a few hours)
(2) What are good drives to read out damaged CDr’s?
