I have modified the Apple COPYA program so that I can specify the number
of tracks that I want to format a disk for.  The main drive that I use
today is a Laser 40 track drive and most of my other drives can use up to
39 tracks, a 15% increase in capacity.

I personally pointed this out to him long before anybody on the list did.

For a couple of years I used a hole punch in order to use the back side
of a disk.  Then 20 years ago I bought a 'NIBBLR NOTCH' which was an
adapted hole punch (along with software to make a disk use 36 tracks)
that punched square notches at the proper place so you could use the back
side of your disk.  I still use it today as the only media I still use
are 5.25" disks.

I all this time I still have never had a floppy that wasn't perfectly
good on the back side. 

I have well over 600 disks.  A few hundred of them are of the monthly
magazine 'SOFTDISK', which started out using both sides of 1 disk, but
soon used both sides of 2 disks, and later went ProDOS.

of tracks that I want to format a disk for.  The main drive that I use
