[Coco] Disk drive question

[Bill Pierce]

Yes, I've used the same drive as the one formatted/copied to. The thing to remember here as far as the 40trk/80trk drive thing. I am running stock OS9 Level I. The drivers are ALL set to 35trk SS. So the type of drive should not matter.. the same in DECB. It's stock DECB, no 40trk patches. So any formatting done is 35trk SS.

Are you useing the new disk in the drive it was written in?  If a drive is 
ut of alinement it should still read it's own disks.  Also, a disk written 
n an 80 track drive will not be readable on a 40 track drive.

> The J&M controller & the 3 drives are the same ones Michael Knudson (it's 
 his old system) used for years while developing Ultimuse3. I also have an 
 FD-502 that I've tried. The system hadn't been used except an ocassional 
 boot up in over 10 years. Nothing in the system was changed and it booted 
 (minus the hard boot due to missing boot floppy) when I first recieved it. 
 As I was trying to figure out the system and what I had recieved, when 
 things slowly started to fail. Keyboard was first (dry rotted pads on the 
 Eagle keys) then the drives started to slowly fail. In DECB the computer 
 itself runs fine. I have even loaded in ML programs, Lyra for instance, 
 and they run as expected. DSKINI and BACKUP seem to work but when I go to 
 read the new disk, they error out. OS9 format shows errors while 
 formating. Sector 00 being a constant in the errors. Assuming sector 00 is 
 not writing, I would also assume sector 00 is not reading therefore boot 
 fails in OS9 Lv II. Does os9 lv I use sector 00 in it's boot as well?
