DReading a QRST5 720KB 3.5" Disk Image
I have a program which needs to be written on a 720KD 3.5" Floppy with qrst5 in order to work. I ordered some such floppies, but am in a hurry and would rather do a software fix. Any tricks for reading such an image so I can get to work? - = - Vasos Panagiotopoulos, Columbia'81+, Reagan, Mozart, Pindus, BioStrategist http://ourworld.compuserve.com/homepages/vjp2/vasos.htm ---{Nothing herein constitutes advice.

NOTE: the hole in the corner of a floppy case with a sliding cover is the "Write Protect" hole; you need to cover the hole in the other corner to emulate a 720 KB floppy. Some drives detect this with an LED and almost any covering of the hole will work. Other drives use a mechanical switch so you would need a fairly stiff cover, like several layers of tape.

That is a veryu bad idea. 1.44M and 720M floppies use different signal strengths. You will end up with a floppy that may be unreadable very fast.

Disagree - if it is a "virgin" disk it should be fine; the problems only occurred when converting one formatted to 1 size to another (I think LD to HD but IMWBW and even then I feel this applied only to 5.25" (genuine floppy!) disks).

Disagree Your problem... - if it is a "virgin" disk it should be fine; the problems only occurred when converting one formatted to 1 size to another You're massively confusing what happens with 5¼" floppys with what happens with 3½" floppys.
