[comp.sys.ibm.pc.hardware] Setting a PC on its Side

Robert_Bell@mindlink.bc.ca (Robert Bell) (04/23/91)

I've been using a desktop AT on its side for the last couple of months and have
had no adverse effects so far.Just make sure it has adaquate cooling and is
well supported and not liable to fall over.

Due to desk space constraints, I am playing with the idea of putting my 
desktop style AT-size computer on its side, vertically, like a tower case.

I have seen this done before, but I am hesitant to take a computer designed
to function horizontally and ask it to function vertically.  Problems that
come to mind are:

1)  Proper Cooling

2)  Proper Functioning of Hard Disk and Floppy Disk Drives

I am concerned about long-term reliability.

Does anyone out there have any advice on this subject?  Any personal
experience and observations?

Thank you,
Dan

 I have done this at home and almost all the PC's here at work are
setting this way. The only possible problem I have even heard of (but
never experienced) is that you might want to reformat the disk with
the machine on its side.  One of the newer disk utilities could do a
low level reformat and data rewrite with no problem. We have not even
done that much. No problems in over 50 PC's. Good luck. :-}

The difference in air flow is negligible.

You can put your computer upside-down and the hard disk should still
function perfectly (assuming it did before, that is).
Floppy drives are much less sensitive to shock than hard drives.  You
should not worry about them.

>I am concerned about long-term reliability.

Your computer hardware basically doesn't really care how it's rotated in
space.  It does care if it's being kicked, though, so if you opt to mount
it vertically on the floor be sure it's safe from abuse.

it's not clear you can *assume* these PCs were designed to function
*only* when placed horizontally.  i have an original IBM PC/AT which
is oriented (like most) to sit on your desktop.  a little-known
feature was a floor-stand for the PC/AT which makes it stand on the
floor just fine.

I have several PC's in my department sit on their side for years and has
no problem so far...

   Time out!  Irregardless of your experiences, most hard drive
manufacturers specify that the drives will function at any angle
UP TO 90 degrees.  Upside down is a no-no.

   As to computers on their sides, I asked the Gateway techs about this
when I got my desktop AT.  The answer I got was that all the techs
their have their computers on their sides beside their desks with no
apparent harm.

Actually, the orientation of the hard drive is important. According to my 
Seagate manual, it is OK to have the drive mounted horizontally on either
side, or with the circuit board down.  Mounting the drive vertically on 
either end or with the PCB facing up, are 'prohibited' orientations and 
operating the drive in these positions will void the warranty.

Some computer manufacturers place the hard drives on their sides in the case
to save space. I recommend checking the orientation of your drive before 
turning the computer on its side.

I've had a desktop computer sitting on its side on the floor for almost
three years.  Every slot is filled (near-maximum heat generation).  This
machine is four years old and has never had a hardware problem.  Long after
I made the position change I read something in PC Magazine that makes sense.
All bearings have some clearance.  If you take a hard disk that was
low-level formatted in a horizontal position and rotate it to a vertical
position, the position of the heads relative to the bits on the platters
will change slightly.  It may be a good idea to do a new low-level format
after changing position.  I run Gibson SpinRite periodically to do a
low-level format anyway, so my experience doesn't confirm or disprove this
concept.

Well, I just don't have enough space on my desk, so I had to put my PC on
it's side too.  I haven't noticed any problem either.  Actually, I think
position is even advantagous (sp?).  I have a hard disk in one of my ext.
slots, so in the ''normal`` position, it would turn vertically.  Now that I
have the computer standing on it's side, it turns horizontally (the hard
disk, I mean), which, I was told once, is better for the drive.  One problem
is, though, that my 5.25` drives are now in vertical postion, but since I
do not use them as frequently, I think it does not do any harm.
And fall over it won't either, I have it standing between the table and a
shelf :)

Greetings, Arne

I've seen at least one disk drive manual that said something to the
effect that you could place the drive at 90 degrees, but flat and
upright was the most preferred position.  

I can probably dig up the reference if necessary.

   About the only problem I've had with standing a PC on it's side is
the danger of static damage if it's not in a stand of some sort - very
likely if you are trying to put it on Nylon carpet.  (Don't flame me,
I didn't do it, I had to fix it).

Wasn't the case EARTHED? 
And most stands sold are PLASTIC, making the inclusion of one irrelevant.

(Ive had my pc sideways for 2.5 years with no hardware probs - oh yeah, my 
 carpet isn't what i'd call "static free" either).
