[Coco] Disk drive question

[Bill Pierce]

I've tried the drives in different combos. individually as well. For the most part I can't even boot from a single drive except for a Level 1 v2,00 system master boot. Seems I read somewhere long ago that the RS factory disks were written to in a manner that even if your drive was in slight miss-alignment that in most cases the disk would read. This was for the fact that no 2 drives are exact in alignment and they wanted no problems. Since the RS disk will boot and no "created" disk will boot, it makes me wonder about alignment.

> On another note, are there any special jumper settings needed to use a 
 Coco 5.25 drive on a PC? The 3 drives I have are a 5.25 40trk DS (D0), 
 5.25 80trk DS (D2) and 3.5 80trk DS (D1). I do have a couple of old 3.5" 
 1.4meg drives that came with PCs. The drive is set for drive 0 on the 
 Coco.
This may be your problem. As I recall, a 80-track disk only allows you to 
se 3 drive descriptors. When I had my CoCo3 I had 2 40-trk 5.25s and 1 
0-trk 3.5. I'm not certain, but trying to use 2 80-trk drives may be what 
s causing your problem. Someone who knows more than I can say for sure.
