I was initially thinking the same thing, I had it connected to the top
connector and set it properly(DS2). It still was having problems. I
played with it some more after you said it and apparently the diag
disk assumes that you always have at least a DS1 drive. So now I'm
past that point. Now option 1 completes successfully. In option 2, I'm
able to Format the disk, but when I try any of the other options (even
rotational speed) it says:
UNABLE TO READ THIS DISK AT ALL.
REMEMBER THAT THE DISK MUST BE FORMATTED BY THE "F"
OPTION BEFORE THEY CAN BE USED BY THIS DIAGNOSTIC.
The initial try was with DS DD and 80 tracks. I also tried SS SD and
40 tracks, with the same error.
