Gents, I would not normally post 'please help me fix' type questions here but this one has me stumped. Some may already have seen the thread on vintage-computer forums here: http://www.vintage-computer.com/vcforum/showthread.php?34572-8050-Floppy-Repair In a nutshell, drive 1 works 100%, drive 0 will read and write but not format. It usually stops on track 1 with a #21 read error but occasionally will go as far as track 3 or 4. If I swap the mechanisms, the problem stays with drive1. This implies a problem in the analogue board (micropolis pcb #8050006) but I can't find it and I don't understand what kind of problem would allow it to write but not format. I know the mechanisms are good and well aligned and, as the drives read OK, they are properly speed adjusted. Do any of you disk wizards know the algorithms by which these drives format a disk? I hoped this might give me a clue. Rob Message was sent through the cbm-hackers mailing listReceived on 2012-12-01 01:00:12
