Every recommendation (including one to replace the power supply) has
a common factor. In each case, the recommendation comes without first
learning the circuits.

Unlike other drives, the floppy is turned on and off by a switch on
the floppy drive controller. Switch on controller connects to floppy
via a cable. If the cable is reversed, the floppy 'sees' a closed
switch and powers on. If cable is not reversed and switch is failed,
then floppy 'sees' a closed switch and powers on. If cable is
disconnected from controller (power connector remains connected) and
floppy powers off, then problem is directly traceable to the switch on
floppy controller.

Rather simple analysis when one first learns the interface signals -
when one first asks why a reversed cable would also cause same
symptoms. Notice how many knew the symptom but never once asked why.
'Knowing' without also knowing 'why' explains so many replies without
a useful conclusion.

Report what happens when you perform those above tests.

That is pitiable. Actually, it is just an arrowhead that I see, though.
Look for anything at all-- a dot or a notch, maybe, on the floppy drive
case at one side of the floppy connector. That is where I would position
the red stripe.

So... although the drive never seems to stop spinning, it actually works
as normal otherwise? Or, are you just saying it will spin but not work
either way? Did you ever say whether it works? How does the drive behave
in DOS Mode, as I asked earlier? And don't forget this...!...

(1) "Control Panel, System, Device Manager tab"
(2) Open the "Disk drives" branch,
(not the "Floppy disk controllers" branch).
(3) D-Clk the floppy drive that appears under it for Properties.
(Mine is "Generic NEC Floppy Disk".)
(4) At the Settings tab, ensure "Removable" is checked.
(It just sounds as if that might relate.)

That one you ought look at in Normal Mode.

It is a mystery why the floppy won't cooperate.

OK. Anyhow, I couldn't quite fit in it last time I tried! That was an
interesting thought Myers posted in your other thread...

......Quote...........
The power supply cable carries two voltages,12 volts for the drive motor
and 5 volts for the electronics. If it is connected in reverse, the 12
volt
line is applied to the electronics, which may cause permanent damage.
I suggest you try a known good floppy drive, making sure to connect
the cable correctly.
......EOQ.............

I hope nothing like that has been going on with your power connector!
It's hard to describe the power socket on this SONY MPF920-Z floppy
drive in my hand. There seems to be a deep plastic slot under the 4
metal prongs. One side of the slot actually doesn't touch its wall. I
guess it depends on the shape of the plug whether it will fit just one
way-- but I can't see that! Good luck!

Give me your home address, troll, and I'll send you the $15 that
the new one will cost you. Plus I'll know where to find you so I
can punch you in the mouth next time I'm there.

Of course, once you GET a new PS (i.e. SAY you did) there will
be a new problem with "your floppy drive", won't there?

Uhuh! Could be the floppies are somehow sensitive to the increased
power, (I'm guessing). Can you go back to the removed one, or was that
dead? I hope the floppies haven't fried now!

First, if your floppy disk problem was created by a power supply,
well, what from a power supply would cause your 'always on' problem?
Nothing really. A controller orders a floppy to power on. But your
floppy powers on each when not connected to that controller. Actually
controller talks to a transistor to power the floppy on. But that
transistor (apparently) is always on (shorted) whether ordered on or
off.

When I would repair floppy drive electronics, I would now know the
small location to study and repair. Obviously you are not going to do
that. Your floppy drive is defective and must be replaced. No way
around that apparent conclusion.

Second, the multimeter is so complex that only Kmart shoppers would
buy one for a trivial $20. A significantly useful tool that requires
complex training. Dial (select) what you want to measure, touch
probes to conductors (wires), then read a number. Now you are an
expert multimeter user. Meter is that complex. If you cannot use a
multimeter, then never consider an Ipod. Ipods are far more complex
also require people with Kmart abilities.

Third, the meter measuring two voltages to the floopy drive might
have provided some useful information. Probably not. Extremely
doubtful. Meter readings would not have solved anything since your
test with cable removed says the failure is the power on circuitry
inside floppy disk..

Fourth, a defecttive power supply can still boot a computer. The
better informed technician uses a meter and two minute procedure to
confirm that replaced power supply is working properly. Just another
in a long list of solutions provided by the meter - which are not
needed for this 'simple' failure. Simple: as in why were so many
replies necessary? Well, others fix things using wild speculation
which explains so much wasted labor. Neither you nor I are going to

Actually, he did replace the drive. This is a long thread and it is easy to
miss what he did and did not do.
I believe that he: (not in any particular order after he replaced the PSU)
1) replaced the ribbon cable
2) reversed the ribbon cable at either end and at both ends
3) checked to see if his FDD Controller was listed (Safe Mode only showed
one)
4) rechecked his PS connection to the MB
5) rechecked his power supply connection to the FDD (not sure if it is
possible to reverse that connection)
6) replaced the FDD with a 'new' one
7) removed the ribbon cable from the new FDD and still had the problem

Would a reversed polarity on the power supply to the FDD cause the above?

That solution was already tried earlier in the thread, and the user stated the
problem still exists with a new floppy drive. There was also an earlier thread by
ther same user on this subject, where it was originally suggested.

The suggestions in this thread are not based on "wild speculation" despite how you
may perceive it. I do look forward to your next reply, as to why the problem
remains even with a new drive, and with the data cable disconnected.

I'm not convinced thanatoid is 99.99% a troll. I think he still can be
exorcised with hot coals & a prayer!

I'm going to hunt him down for an exorcism with prayer & hot coals. Soon
you may remove him from your kill-file for being cured or for the
redundancy of it.
