5158.0. "Noclick Needed for 2.04" by VERGA::MACDONALD (Home of Digital Realtime Pubs) Wed Oct 30 1991 12:56

    Are there any NOCLICK utilities available for the A2000 with V2.04.
    The "several" that I have appear to have no effect on V2.04.

    I will upload a version of NoClick that I use on V2.04.  Seems to work
    fine.  Docs are included...

5158.4Why do floppies click?AMIGA::RIESOS/2 = Half an Operating SystemMon Nov 04 1991 14:3510
Here a question, and I imagine it has been answered in this conference somewhere
before, but why do AMIGA floppies have to click? I know that it is done to
see if you have removed, inserted a floppy. I am assuming that they have
not hardware detection for this?

If you run some form a noclick software, do you lose something? Does everything
still work as it should? If it does, then why do the drives need to click?

Just wondering,
Frank

You're correct - there is no hardware to detect floppy insertion. At least,
there isn't a standard for it.

The floppies click because they step the head, and check the result to see if
there's actually a floppy there. The "noclick" hacks all step the head
the opposite direction, which on most floppies does nothing, but does
return the appropriate status information.

Some floppies actually *do* step the head the wrong way, resulting in
a) a click, and b) slamming the head against the stop. This can damage
the floppy drive. That's why CBM doesn't make that a standard - they'll
get the blame for damaging the drives, even if none of the drives
they've shipped behaved that way (I believe that all drives shipped by
CBM are fine with the noclick utilities).

If you run the noclick software and your drives keep clicking, quit
running it. Make sure you've got a vesion for your OS; 1.3 and 2.0
noclick utilities don't work on the wrong OS.

Commodore has sold drives that behave both ways.  The floppy in my
early model B2000 works fine with noclick utilities, but my old
A1010 external floppy left over from my Amiga 1000 does not.

The symptom is that the noclick utilities don't prevent it from
clicking.

I keep my floppies silent via a blank disk in both.
