Your Most Damage-Resistant Hardware?
questamor writes "After reading the recent Slashdot article linking to drivesavers and their list of damaged hardware that was still recoverable, I'm curious about the worst things slashdot readers have done to their hardware and still had it work. So far I've been lucky, and in more than a decade of owning computers I've hotplugged almost everything except a CPU (sometimes accidentally, sometimes through laziness) and never knowingly broken anything. What have you all done to your machines? I imagine there are many stories of dropped, drowned, stolen and generally abused machines still working and doing their thing; or at least, able to be brought back to a working state"
The amazing part is that I took it out, put it back in properly grounded, and it's still running! (That was about four years ago, I think).
Well, not me, but my mother. About 3-4 years ago she drove her Explorer over her (i think) Satellite.
:)
It looked horrible, all cracked and what not, LCD and keyboard destroyed.
But for grins I hooked it up to an external monitor, keyboard, and mouse and she booted right up.
And I've been using Toshiba lappies ever since
Looking for hardware (Currently need: Large Etch-a-Sketch) Have one? See my journal!
Not sure if this actually qualifies, but here goes.
:^)
A friend of mine who frequents here once had a video card that would not fit into his case. I forget the exact model. He called up the manufacturer and asked them what he could do. They told him that everything on the board past a certain point was just redundant, and that it could be safely removed without affecting performance. Naturally, he got that in writing before taking a hacksaw and hacking off almost half the card! It worked when he finally got it in.
Nope, I didn't believe him either.
Slackware forever. Honestly, what else would you trust when it absolutely positively has to be stable, secure, and easy
About 4 or 5 years ago, my best friend and I had just returned from what's referred to as "first saturday" in dallas (everyone goes downtown and sells hardware for cheap on the first saturday of the month).
We were pretty anxious as we had both just bought brand new machines... so we headed over to my house and started building the computers.
I swear that there's nothing better than the first time you turn on your computer after you've successfuly built it. Anyway, as soon as my friend was finished building his, he turned on the machine, and I kid you not, the motherboard caught on fire! the details of how we stopped the small fire alude me at this point, but after we finally finished putting it out... he turned it on again, and it worked perfectly!
arcane for life
My coworker took a replacement monitor up to her. Then he turned the monitor upside down (after unplugging it of course), drained out all the water, and instructed the secretary to let the monitor dry in the corner for a few days.
A few days later he connected the formerly hydrated monitor back to the computer and everything worked fine.

About 12 years or so ago, my father's friend had a housefire. The heat warped the monitor, attachable 3.5 inch drive, and the keyboard. The whole system was blackened by the smoke and then completely hosed down by the firefighters. He told my father he could have it for spare parts, but when my father cleaned a few connections and plugged it in, the bugger worked! We were both amazed at the amount of damage done to the casings and hardware(the 3.5 inch floppy had SERIOUS issues ejecting.) That's probably the worst I've ever seen done to a computer.
My friend did this, and the amount of smoke from just one wire on the ribbon was amazing (to me anyway, he didn't seem to take it the right way).
It was like someone took a knife and sliced the ribbon all the way down, making two parallel ribbons. You ask: was everything OK afterwards? Yes! The scsi card and all devices were fine. Did his scsi card have a fuse on the terminator power wire? Obviously not. The event was locally named the "Lonergan SCSI terminator power-wire-fire". Boy I can't believe how tough some of this hardware is. The only HD I've every blown was because I let the onboard controller touch the case chassis. Spark! I've got cables the wrong way round, forgotten to plug fans in, hotplugged stuff I shouldn't... I can't kill anything!!
Some years back I worked for a company that had several large HP plotters. If you're not familiar with them, they are basically large ink-jet printers, capable of printing on sheets 48-inches wide and up to tens of feet long. They're obviously useful for printing CAD drawings, GIS maps, etc.. And highly-precise ones can cost big $$$ (precise meaning the scale of the drawing that ends up on the paper is accurate to less than .01" of distortion over the 48" width of the paper) - at the time at least, these plotters cost over $10k each.
Anyway, we grew out of our office space, and we therefore rented new space, and started moving. Myself and another college-age guy were in charge of moving all the computer equipment, since we were the "geeks". We took a couple of these plotters - which stand about 4 feet tall, 5 feet long, and only about 8 or 10 inches deep - and all of the mechanics are along the top - so they're tall and narrow, and very top-heavy - and loaded them into the back of a small pick-up truck, and headed down the road. Being a dumb 20-year old (and driving like one) we zipped around a corner, and both plotters lauched themselves over the side of the pickup-bed and bounced across the road. Needless to say, we nearly crapped our pants!
We stopped to pick the "garbage" up out of the street, so it would be out of the way of other cars - we assumed that the plotters were a complete loss, and that we were going to have a fun discussion with our boss. We placed them back in the pickup truck (including many broken-off pieces of their plastic cases, a few gears, belts, etc.)
Well, we got them into the new office space, set them up, and snapped back together all of the parts that we could. To our amazement, not only did they "power up", but they actually worked! And not only that, their callibration wasn't off by a hair! In my mind, this was absolutely amazing (and a god-send)!
Aside from looking ugly (cracked, scuffed, and holy cases), there was no problem, and (according to my former co-workers) they went on to work for several years.
I've never been a fan of Hewlett-Packard PCs, but their plotters and printers sure hold high respect in my mind.
My first hard drive I bought used out of "The Want Advertiser", a weekly magazine of classified ads here in New England.
My computer at the time was a Tandy 1000SX, so it had 2 low density 5.25" floppy drives... I spent many afternoons playing the original MechWarrior on this machine.
<DIGRESSION>
The Tandy 1000SX was an IBM PC compatible, but it had some custom hardware: It had sound which was better than the PC speaker (in that it was polyphonic), and some sort of 16-color graphics which was nevertheless incompatible with EGA... so, most games couldn't do better than CGA, but MechWarrior supported both Tandy Sound and Tandy Graphics! Because the processor was a lowly 8088 and MechWarrior was a true-3d engine (one of the first? filled polygons, but no texture mapping or anything), my mechs would take a step every 10 seconds or so... Battles would have taken forever, except for the fact that it was very easy to win in this game: Just take a Locust mech (the fastest), and use only machine guns (which generate very little heat)... It was very easy to run around behind enemy mechs, and then just shoot out a leg (which makes them fall over and die)
</DIGRESSION>
Anyway, I bought a Seagate 40MB RLL hard drive out of the Want Advertiser for a measly $25. (HDs were far more expensive than this at the time). This was a godsend for me because I was only like 14, and my parents did not approve of my "computer habit." I had more money than other kids, although still not much... I babysat 4 days a week after school, 3pm til 9pm, for $10/day.
The guy said on the phone, "The drive works fine, except for one thing: Sometimes you have to turn the power off and on a few times to get it to work, it doesn't always spin up on the first try"... I got the drive, and it worked fine, I almost never had the problems the guy mentioned.
Another digression: The drive was RLL, but I only had an MFM controller (which I had also bought used, for $10). You could hook up an RLL drive to an MFM controller, but you could only address 17 out of the 32 sectors per track an RLL drive had, or something like that... So I only got like 20MB of usefulness, but after years of swapping 360k floppies, I was still happy.
Anyway, the drive got worse and worse over time, until finally I was afraid to turn the computer off because the drive would take sometimes 20 minutes of monkeying to get it to turn back on.
One day, I just couldn't get it to spin up for the life of me. I let it rest for awhile and tried again, and it still wouldn't work.
What I ended up doing always gets some people calling bullshit, but it's the truth: I took the case off of the drive, and I could see the platters and the arms and everything right there... I tried turning it on and I saw how it sort of jerked in one direction... So, I started it spinning in that direction by myself, and then turned it on, and it spun up fine, and I could use my drive. I replaced the cover and used the computer and everything was fine. The drive lived maybe 3 or 4 months after this, with me powering it down as infrequently as possible, but it was growing steadily worse in terms of bad sectors... I didn't have scandisk or anything, so every couple of weeks I would reformat the drive (the lowlevel format marked and avoided the bad sectors), and reinstall DOS and the software I used... (I had been used to having no HD anyway so this wasn't such a huge deal). When I finally gave up, more than 60% of the sectors were bad, and the top platter on the stack had fingerprints on it from where I had occasionally slipped while doing the manual spin up.
That's my wacky hardware story.
Messing around inside a power supply while it was on, wondering why the fan wouldn't spin.
:)
When i came to, I was on the floor and the lights were out.
I'd almost killed myself, and this was in australia where we have a full 240V (not wimpy 110)
The power supply still worked, but I wouldn't touch it again
--- I hate my sig
IBM used to make very solid hardware.
Case in point a few friends were ridding in the suzuki version of the Geo Metro and didn't have space in the car for the PS/2 so they put it on the roof and someone put his arm out the window to hold it.
The get most of the way home when the thing blows off the roof while the car is going 110Km/hour and bounces twice on the shoulder before going into the ditch.
They stop and pick it up and when they get home they plug it in.. still works.
Pity they don't make them that solidly anymore.
The most drastic case I've ever come across was a motherboard that I installed without grounding. Turned it on, nothing happened for a few seconds, then "POP!" Smoked the thing. The amazing part is that I took it out, put it back in properly grounded, and it's still running! (That was about four years ago, I think)
I'd expect that you had a capacitor fail. I don't know what that would have had to do with forgetting to "ground the motherboard".
The black leads in your AT/ATX power supply connector are the power supply grounds. The RF grounds are provided when you screw the motherboard down into the case - the little pads around the screw-holes are connected to the motherboard's ground plane and serve to take care of that requirement (although, as most of us know, a motherboard will run outside of a case - it's not recommended for RFI reasons).
If it was a new motherboard, probably it was defective. There are generally lots of capacitors on motherboards, to provide RF bypassing and power supply filtration. If an electrolytic capacitor (aluminum or tantalum) is installed backwards - or has too low a voltage rating - then it will fail. Aluminum (ordinary) electrolytics tend to fail leaky - which means that the capacitor will dissipate energy and heat up, sometimes exploding, but often just remaining there. If they pop, they often remain shorted, and cause your power supply to shut down, or damage other parts of the circuit.
On the other hand, tantalum electrolytic capacitors (generally small yellow-orange rectangular surface mount) will tend to fail shorted. They eat up a lot of current, generate a lot of heat, and pop. Once they've actually exploded, they tend to be open circuited, so they're effectively no longer there.
If this was something like a bypass or a filter capacitor, your motherboard almost certainly will no longer work as well as it was designed (ie. RF emissions, susceptibility to RF noise or power supply ripple, etc.) but if it still works well enough for you, that's good.
All the same, I'd be taking a look at what failed and replacing it. You need a very steady hand and a good iron with a clean tip, but you can replace the defective capacitor.
As for the likelihood of a motherboard leaving the factory with a badly placed or wrongly-rated capacitor, well, sh*t happens. In the late 1980s, Toyota shipped over 10,000 Corollas with missing passenger side front speakers. That's a little easier to spot than a shipment of mislabelled capacitors, or accidentally putting a spool of caps into the pick and place machine the wrong way around.
Fire and Meat. Yummy.
I had a floppy disk somewhere-- It has been dubbed many things in its time, but the most common is the Floppy of Impending Doom.
/Ex
Okay, so here's the story of the floppy of Impending Doom.
When I was 11ish, I met the first guy that programmed-- he programmed basic among other things, and I thought he was the coolest guy-- We kinda played around a bit, and eventually, he gave me a floppy full of dumb little games written in basic-- Not well written, mind you, but when you're not supposed to touch the computer, any game is cool.
Anyways, he gave me a floppy full of games. Fast forward a couple years, I had moved, and didn't have contact with this guy. I had met another guy who was into computers, and I ended up giving him a bunch of stuff on disk-- hex editors, game trainers and their ilk. Having no other disk accessible, I ended up giving him the disk of impending doom.
Fast forward, another year and a half, said friend had passed that disk around, and I ended up getting it from a friend who got it from a friend, who got it from some guy I don't know, who got it from another guy, who got it from my friend. I realized there was something special about this disk (it went through like 7 people that time. It had my original label on it, which is how I know it's the same disk.
The disk was used for a couple years a couple times a week, I didn't have a printer, so I would bring it to school/a friends house to print stuff. Eventually, I left it in the computer lab.
It made it's way around back to me, after more than 2 years, right before I graduated high school. This disk is now so old, and has so many writes on it, that I didn't trust anything I ever wrote on it-- Yet somehow it still worked fine. I brought it up to college, and, because my computer didn't have a floppy drive, I didn't use it... I ended up giving it to someone who needed it in the computer lab (I worked in the labs). Three years later, about a month and a half before I drop out of school, the disk turns up yet again. Someone left it in the computer lab, and so I grabbed it again.
At the time I was working on a search engine for a small non profit organization, which had me moving all around, so I used this disk to port my writings from place to place. I ended up leaving it with my non-profit supervisor (I was volunteer, I was having a bad time at the time, so I gave up the stuff, I didn't get paid anyway).
I'm sure that in a few years, I'll be living on the streets of some large city, and I'll find it stuck to gum in a trash container. It'll still not have a bad sector.
One time I accidentally dropped a floppy from about 2 inches above the desk, and yet it still worked! (although I did have to completely reformat, losing the data already on it)
You just reminded me of something that happened to a friend in the late 1980s.
We were die-hard members of one of the Texas Instruments TI-99/4A user's groups. He had his PEB (Peripheral Expansion Box) at a meeting, and was carrying it on a cart up a set of stairs. He was at the top of the stairs when it feel off the cart.
Before I continue, a word on the TI-99/4A. If there's a nuclear holocaust, I have every faith that the only survivors will be the Jews, Dodge Darts, McDonalds uniforms, and the TI PEB. You see, Texas Instruments built them out of stamped steel, with each card housed in a cast aluminum case. They were overbuilt for military use, let alone as a "home computer".
So, the PEB went end for end down the terazzo stairs. Bang, bang, bang. Little chips of terazzo breaking off the corner of each step, and a few small dents in the PEB.
He picked it up and shook it. Nothing sounded loose inside, so he hooked it up, and it still worked. Until he tried to save to a diskette.
The old full-height Shugart 5.25" double-sided single-density diskette drive now had a new feature. He could format a diskette, flip it over, and format it again. One of the heads was now halfway between tracks, so the net effect was that he had a four-sided diskette. 360k to a 5.25" diskette, while the rest of us were only getting 180k.
Fire and Meat. Yummy.
Pity they don't make them that solidly anymore.
They do. I've got a 4 year old Thinkpad that I've dropped countless times from normal table or standing height (a couple of times while it was on and the hard drive spinning!) and it's only got a single small scratch on the top of the casing to show for it. IBM still makes probably the toughest hardware out there, and they don't even advertise the fact - it's just assumed. IBM makes hardware the way people expect hardware should be made. (Though it's true that their PC keyboards are no longer built to the same standards as their old Model M's, but then most people don't even seem to like typing on that kind of keyboard anymore. I'd never give up mine, though.)
Just to compare, my wife has a Fujitsu FMV-Biblo, a made-in-Japan notebook with a metal casing. Her system has hinges that no longer work (she needs to prop up the screen on something) and the speakers crackle when the network's being used, apparently due to a bad connection. My IBM still looks and works as good as new despite the abuse it's taken.
I have a car audio amp that survived a drive-by shooting. It's a crappy no-name knock off amp too. The amp has 2 nickel sized bullet dents, but has run fine for the 4 or so years since. My friends car was wrecked and he got hit twice, but is fine now.
My office is on Pico blvd in LA (a very busy street). On a smoke break i noticed something orange and toilet-seat shaped being run over by numerous cars in the middle of pico. I ran out to find an Apple iBook (clamshell tangerine). The LCD was hosed as was most of the upper housing of the case. Everything in the lower half was perfect. Mobo, CPU, and hard drive all work fine. I work in a Mac store and waited till someone came in with a liquid spill on another clamshell. Found a nice blueberry one with a fried logic board and cpu, but pristine case. Now I have frankenbook. You cant see it there but the apple glows, the keyboard is half black/half white (powerbook g3 keys and ibook keys) and i have glow-wire around the keyboard and trackpad.

CapsGetPeeled fo Life
I used to work as an engineer in a manufacturing plant for one of the larger computer companies. We would be assembling PC's from components, which would be the first time the boards would be powered up for any length of time. If a cap was going to pop, it would generally do it in the first 10 minutes or so of testing. Sometime's because they were installed backwards, sometimes because they were fractured and a bit of moisture had leaked in, and sometimes just because. When they pop, they do so with a fair bit of force for their size.
This is why you should wear eye protection when you peer over an open computer, especially a newish one!
