I guess one serious question is "Do you want
to have the drive be
insensitive to the media-type hole in 3.5" disks?" While many
people do use 3.5" DSHD floppies with the hole taped over for 720K
use, I do question the advisability of this, particularly given
the terrible quality of late-manufacture DSHD 3.5" floppies.
I'd go straight to Athana. They still make/stock 720k media.
