Can you make another image with SC's warp transfer mode active? In this mode SC can keep the contents of the soft errors like block or header checksum errors. Also, the error info would give a hint if it is a soft or hard error. If SC can't copy the sector, you might have to use Zipcode sixpack. The more primitive protections just checked if an error was present, the more sophisticated ones also read back the contents of the bad sector and made use of it. Of course there are much more advanced protections, but it looks like it is one of those, probably the second one. BTW, who's the "Sister H" that is mentioned in 18,0? And what file starts at the mentioned block 26,2? It's not in the directory... Nicolas - This message was sent through the cbm-hackers mailing list.
