Ok, this is strange.
I ran the disk check, and the program didn’t report anything wrong with the drive. So I quit to TRSDOS, put a blank in the upper drive and attempted to format it- it worked with 0 bad sectors!
Then I tried putting my original boot disk back in, and it went back to its bad behavior once again. I’ve never seen a system disk cause issues with hardware like this before, how is this even possible since the boot disk works?
