Actually the "chunk" that is missing from the right hand side of the
disk is what allows the computer to write information to the disk. So
to format the back side of the disk, in a standard Apple II drive,
you'll need to cut a similar notch in the left hand side of the disk
directly across from the notch on the right hand side. After you've
done that you need to turn the disk over and put it in the drive to
format the back side. Also using MacADT or ADTPro to copy the disk
images to the disk you'll need to turn the disk over to write
information to the back side.
In fact if you've been trying to write the back side of the disk
without first notching the left hand side and then turning it over
it's possible that you been writing over the boot side of the disk
every time.
Just my two cents worth,
Well I didn't try formatting the back side until after I had problems
with booting. So I don't think that's the problem.
I was just afraid that maybe the Apple /// required that the disks have
both sides formatted, or something. I wasn't sure if it had a
double-sided disk drive or not. I guess not.
The Apple /// and Apple ][ have almost identical 5.25" drives. The only
real difference is the analog board within the drive, which is larger on
the Apple /// and has a different cable connecting it to the computer.
I'm not sure what electronic differences there are between the analog
boards.
