And that program did seem to read it more than once. Mayne it would have done better with a different file type, but I had to look for the files that were probably there, not others. > > And then, you can snapshot, repair, etc, the image to your heart content > without a risk of breaking things further. The hex editor I did use directly no the original disk. And it worked. I figured that if something really weird happened as a result of the rather innocuous-looking changes I was making I could always copy it back from the 32G copy I had on my SSD. -- hendrik ___ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng

I have pushed changes for the Visual guides to master and also a few other tweaks including the one mentioned above. That list on the filenaming page is now more aligned with the other iso lists. I also rewrote/reorganized the "Package repositories" partial which appears in several places. I am now going through that entire thread to see if I missed anything.

Hint: in almost any rescue operation, the recommended first step is to dd the whole disk to another place -- doubly so if the source is so small.
