The 1.44M diskettes have a different oxide than the

disks have one hole for write protect while the 1.44M has a second hole. The
new drives sense the hole and adjust the write current for the different
oxide. You can cover the extra hole on the 1.44M disks and formatted it as
720k but this will cause problems (I have been told).
I used to do that for my old Mac SE - cover the hole on a 1.44m floppy
to make it a 720k - and it works ok. It is sort of a one-way deal,
though. I could never get them to format back to 1.44. I also have no
idea what it was doing to the drive. Nothing, I think, as my son still
has that SE.
