DReading a QRST5 720KB 3.5" Disk Image

[vjp2.at]

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?

Depends. Under linux you can do a loopback mount. An other fix is to
down-format a 1.44 floppy disk.

File Manager (Winfile.exe) can format a standard 3.5" floppy to 720KB.

You can format a 1.44MB as 720KB using FORMAT

FORMAT A: /F:720

However, if you already have an image file, disk imaging programs can write
a 720 image to a 1.44 disk with no problems. I use WinImage to do that.

All you have to do is put some tape over the hole in corner of a 1.4
Meg floppy and the drive will treat it as if it was a 720 Kb floppy.

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.

Nope, not when the OP wanted a quick and dirty workaround while waiting for the correct media.

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).

Your problem...

You're massively confusing what happens with 5¼" floppys with what happens with 3½" floppys.

If I told you that I'd have to kill you. And even you wouldnt want that.

And stop that smirking, this is no laughing matter, boy.
