Ok folks, I have found the issue with the format track function. I was writing a preamble of one 0xff followed by all zeros, due to a programming error. With that error, it’s surprising that I could find any sectors at all. Fixed that and the first track is written cleanly and I can read it back reliably. However I must have a bug in the verify track portion of the format function, as the format disk routine quits after writing one track. As RosanaRosana Danna would say – “it’s always something”

Hello world!
Welcome visitors,
I frequently receive email containing questions or comments about the various topics on my Hobby Website. I often incorporate the feedback into website content, but sometimes I don’t take the time to incorporate this feedback. Sometimes I don’t have the answer to the questions posed. I have created this forum to allow visitor’s to feedback and exchange information about the topics on my website. I encourage you to post feedback, information and questions directly to one to my forum’s rather than send me directed email. I will use this blog forum to update visitors on the latest happenings in my hobby world.
Best in your hobby endeavors,
