You can turn the 800 into a 1.4 by drilling a second hole. The biggest problem was often the reason they were formatted to 800kb is because at 1.4 they had sector errors. Going for 1.4 to 800kb (or 720k on a PC) was entirely software dependent. I believe DOS used to let you do it without doing anything special. To do the same on a Mac, you had to cover up the second hole with some tape.
I had to do this all the time when the number of disks I owned was limited and the different computers I had access to contained different capacity drives.

I'm on OSX Lion with a working Floppy USB unit and brand new 3 1/2 disks, trying to install OS 7.0.1 on a Macintosh Classic with a new drive (no current installed OS).
I ran the following command on terminal: dd if=~/OS7/os-6-1.img of=/dev/disk1 bs=84 skip=1
It completes succesfully, but then I encounter the following problems:
1) If I try to re-mount on Disk Utility, it returns an error message saying it cannot be mounted.
2) If I eject it after the terminal command, it says I have to initialize it, because it's not formatted (??)
3) If I start my Macintosh Classic with it, it ejects it and doesn't recognize it as an installation disk.
