[Coco] DSKINI glitch while using physical drive 1 and SDC DOS 1.5

 You could try reading the sectors in reverse order. I did that for a basic program I wrote that was reading tracks from the disk sector by sector. BASIC was to slow to be ready to read the next sector in forward order, but in reverse order the interleave was larger and I could read the track faster.
