I have a Disk II, after a lot of cleaning, I have a disk II reading/writing the floppy disk
but I have some read error on track 34, it's not a bad floppy disk (the problem occurs on almost
all my disks)
I've adjusted the speed, it was a bit slow
but know I have no idea,
occasionally it works and read the entire disk...
but most often it fails on the last track
any idea of what I should to to solve this problem ?
