Just wondering: I see 9114 and 9114A being used interchangeably (mine are
9114s); are they the same or actually different drives?

Thank you for your help.
That is the command I am using on the 41 to try and format the disk.
With a directory size of 60.

Also this article refers to a set of commands for
this drive. The NEWM
command formats a new disk.

Yup, that's all I used to do. Some scotch tape over the floppy disk hole
to
make the system see it as DD. If it didn't
automatically format as 720,
you
could specify size or sector count with
format.com in dos.
Somemedia sensors are optical; use opaque taps.
I did hear folks say it wasn't always reliable (similar to 5.25 disks
being
formated on a high density drive) but I never saw
any problems in my
limited use.
3.5" are 600 VS 750 oersted;
5.25" are 300 vs 600 Oersted;
a low density 5.25 formatted as "high density" won't do well;
a high density 5.25" (1.2M) formatted as low density ("360K") sill self
erase VERY soon, sometimes before you can even get it over to another
machine. We had a college purchasing agent in bed with "Roytype", who kept
giving us "1.2M" floppies ofr out TRS80s; they self erased very soon.
