Actually the PC floppy controller is "sleeping" for a period of time
after the index hole passes by. The track header of a CoCo formatted
disk is quite short, so the floppy controller sometimes misses the
sector header of sector 0. I could improve my results of reading CoCo
formatted disks with a CoCo drive connected to the PC by playing around
with the drive's speed while repeatedly reading sector 0 (in theory just
slowing it down, although I darkly remember, I couldn't really proove that).
Regards,
Torsten
