I burned a floppy drive

[Guest]

Archived from groups: alt.comp.hardware.pc-homebuilt (More info?)

I built a bare minimum box to install Solaris 10 x86 with the
following:

1. MB: Asus A7V8X-X
2. Hard drive: WD Caivar 40GB
3. CD R/W drive: TDK
4. D-link NIC

Since I was not able to connect to the Internet because I did not have
the proper NIC driver, I had to borrow a floppy drive from my another
box so that I could install the necessary driver.

As soon as I re-booted, I smelled something burning and then saw the
power cable to the floppy glow bright red. Turning off the system
power saved me from a major disaster.

Why did it happen? The only thing I can think of it was that I might
have reversed the interface ribbon connection. I wonder that was the
real cause of it. I would not try to reproduce it. Can reversing the
ribbon short the power cable?

A reversed ribbon cable connection wouldn't cause that.

No, that would just make the LED stay lit up usually. If you had the
little 4 pin power connector shifted over an on just 3 pin so either the 5
or 12 volts (depending on the way you had it shifted) was routing back
through the ground, maybe that would do it.

I guess not.

>Can reversing the ribbon short the power cable?

Like the others have said, reversing the ribbon does not cause a
fire. Seems that either the power supply, the cable, or the floppy
to drive is at fault.

Did you reverse the power cable? I would be concerned about the
integrity of the power supply. I would use different cables. If you
use the same floppy disk drive, of course be very careful.

Good luck.

I suggest getting a proper PSU...that one sounds like a fire hazard, not
to mention the potential to damage the rest of the computer.

I'm going to die rather sooner than I'd like. I tried to protect my
neighbours from crime, and became the victim of it. Complications in
hospital following this resulted in a serious illness. I now need a bone
marrow transplant. Many people around the world are waiting for a marrow
transplant, too. Please volunteer to be a marrow donor:

This does not necessarily mean the psu is dangerous. At 5 Volt, it can for
example give 20 amps (perhaps even more). 20 amps are enough to start a
fire.

Could it be that there has been some sort of short-circuit at the floppy
drive? Perhaps the pcb touched the metal of Your case and thus made a
short-circuit. Or perhaps a screw You dropped and that got stuck somewhere?
I have sometimes misplaced the ribbon cable and the worst consequence was
that the pc did not boot up anymore.

What I would try is first put the drive in an old (disposable) computer and
try if it is still OK. If yes, connect it to the new computer, put it on top
of something isolating (a plastic box for example), and try it again.

I once had a short circuit on a mobo because of short-circuit with the case
by means of one of those brass distance-things (sorry, English is not my
mother tongue), and it gave a lot of smoke and an awful smell. There's much
power in a computer psu, and that can be a fire hazard, but if the current
is not enough to blow the fuse, it might still be enough to set something on
fire.

Good luck,
Rene

I've never seen reversing the ribbon cable do anything other then cause the
floppy drive to be inaccessable and the light remains on

The original poster was asking whether reversing the data cable can
short the power cable. The data lines probably cannot source or sink
much current, so it really doesn't matter to what they are
connected. The data cable wasn't overheating. The question is
whether the confusion caused by reversing the data cable can cause
the power cable to short. Conceivably the confusion could cause the
drive to act erratically and produce an unforeseen large
current/power consumption and abnormal wear, but it won't cause the
power cable to short.

a brand new floppy is £4.00 just go buy one

Blowing the output and causing the cable to glow bright red are two
different things.

And you counted all the "data lines" in the world, how?

There is absolutely nothing to the term "data line" that suggests an open
collector output and to suggest otherwise is simply wrong.

Which was made clear and fully explained in what you sniped. In particular
"In the case of a floppy, however, the outputs are open collector pull downs."

But then, if you hadn't snipped that out it would have been even more
obvious you're just trying to be an ass.

Yes, they are and no one suggested otherwise. But if you're trying to imply
that blowing an output can't result in a failure that causes a chip to
pull excessive current and burn a trace, or cable wire, then you are sadly
mistaken.

Yes, it's obvious you're just trying to be an ass.

Logic signals typically don't drive much of anything except logic
inputs. It's a well-known fact.

Open collector or not, low current (given the context) is common.

Check up on "data line" containing busses and you'll discover they aren't
all open collector.

Which was the point here: That "data lines" does not mean "open collector."

"Low current' when operating properly doesn't necessarily mean 'low
current' when busted.

No, it simply proves that yours was, or else you wouldn't have had to snip
in order to try and make yours sound rational.

It had to do with the message I replied to. And if you can't follow it then
stop making an ass of yourself.

I somehow missed this thread before, but I managed to burn up an IDE pc
board (the one on the bottom of the drive) several years ago by somehow
getting the power plug reversed. As soon as I turned the computer, it
went "poof!" Fortunately I had another drive exactly like it and was
able to recover the data by swapping the pc board.

Do you know, in 14 years of building PCs I've experienced that a sum
total of ZERO times? And it'd still not make a floppy cable glow...

You've never experienced a "data line" that is actively driven?

Boy, you must not have looked very hard.

Do you think that using double quotes instead of single quotes is
going to make your writing style like any less weird?

If you find a site on English grammar somewhere it will explain to you what
double quotes mean.

No, I've never experienced a floppy drive die because the cable was put

Neither have I. However, it is not because "They're DATA lines," as you
claimed. It is because they are open collector, as I explained.
