Ha! Why should the Pentagon read 1.2M disks? Is it special? Or did you
connect the drive to it on 1.2 without installing 720 on it?!? Although I’m not very good at this - maybe this is possible...

Here it is somewhat simpler and more difficult at the same time. You need to find
an HD/LD (High Density/Low Density) jumper or something similar on the drive, and move it to the Low position. After that, you will be able to work with both 720 disks and with
megabytes (though if they are not formatted to 1.2, the controller
cannot read them).
Good luck !

and Pentagon rearranged :[= ]
Or will my PC mark them up differently? I set it to 360K from the bios.
With respect Vlad
