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!
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!!
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
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.
