Ha. I lost a bit of hair when I received a batch of 8" hard-sector disks and tried to make sense of them. What were obviously sector headers didn't line up at all with any of the sector holes. It wasn't until I got to the bottom of the pile that I noticed that one was a soft-sectored disk. To make a long story short, it's possible to set some drives for hard-sectored operation, with sector pulses output to a different pin than index pulses. If one simply ignores the separate sector output, one can use either soft- or hard-sectored floppies in soft-sector mode. I did verify that this is exactly what the customer had done. --Chuck
