Cat Forum / Cat Anecdotes / May 2004[OT] Exploding CD
Last night, there was suddenly an aweful noise from the kitchen. Joel rushed over to find it was coming from the computer, specifically from the CDrw drive, which had suddenly turned itself on (otherwise the computer was idle, flicking through its screensaver, and had been for several hours). He pressed the "open" button opn the CD drive, at which point htere was a loud "pop" noice, and a few peices of a shattered CD ROM came out on the tray. The rest of the shattered CD ROM had to be be extracted by pulling hte CDRW drive to peices. Now I know virii can ruin *software* but I can't for the life of me figure out what on earth happened to cause the explosion of a CD ROM, e with a commercial, high quality, expensive game on it, at that (Joel is Not Happy at the loss of his game, which he hadn't even finished yet). Can anyone offer an explanation, and whether its likely to happen again? As it is, we don't want to put any CD in there that is important and can't be replaced, which effectively means we don't have a working CD drive anymore, let alone something that can *burn* CDs. And with allt he pictures of the Yowlet we are taking, its *very* important that we can burn on a regular basis, just in case for some reason this HD also goes crash that we still have a copy. Is it time to bite the bullet and by a new RW drive, or is it one of those things that is a freak of nature and is never likely to happen again? Yowie I'd never trust it again. At least not with an irreplaceable game CD. This has to be even weirder than the time my monitor burst into flames. Jo > Last night, there was suddenly an aweful noise from the kitchen.

I found their episode guide, and it's the second show they did: http://dsc.discovery.com/fansites/mythbusters/episode/episode.html  SignatureThe ONE and ONLY lefthanded-pathetic-paranoid-psychotic-sarcastic-wiseass-ditzy former-blonde in Bloomington!

Those spin up to 30K RPM. IIRC, the Mythbusters were up near that 30K RPM when the first disk (which had been damaged (microwaved?)) shattered. But it got to the point where every CD they spun up to speed, including new and undamaged ones, shattered. Some of them even dented the metal case that's around the CD drawer inside the computer's case. This obviously wasn't a "myth" worthy of being "busted" because even the guys at the computer store told them they'd had several machines brought in for repair after it had happened. Here's a couple more links about it: http://www.fujitsu-siemens.co.uk/rl/servicesupport/techsupport/consumer/top10/cd crack/cd1.htm http://www.hifi-writer.com/he/misc/killercds.htm Jeanne Hedge, as directed by Natasha http://www.jhedge.com Most incredibly interesting. Currently my tower is sitting sideways on the desk, facing the wall rather than the room. (two towers and I seem to mess with the wires more than I do with the front, go figure) Maybe I'd best just leave them that way.

Mine faces front, but it's also several years old and not *that* fast. :) During the Mythbusters episode, someone (an industry "expert"? the computer repair guy? a Mythbuster?) commented that shattering disks still probably weren't all that dangerous because pieces aren't flying through either the metal case around the actual drive or the computer case/tower itself. I personally would have a problem if my optical drive throws up so many RPMs that it destroys the material it's supposed to be reading from! If you get a chance to watch the episode, it's pretty wild viewing. I have the impression they thought there wasn't going to be anything to it, or they'd have to pre-damage CD-Roms to get them to break. Boy did they look surprised when just about everything started shattering!

Those spin up to 30K RPM. Thanks, that's such interesting information. A few years ago, a friend of mine who had his CD rack near a radiator asked me if I thought the heat would damage his music collection. I told him that CDs are made of polycarbonate and acrylic, and are exceedingly tough. I wouldn't have believed that a CD-ROM drive could destroy one! >>According to this 2002 article: >> [quoted text clipped - 8 lines] >CDs are made of polycarbonate and acrylic, and are exceedingly tough. >I wouldn't have believed that a CD-ROM drive could destroy one! Yeah, it's pretty amazing, isn't it? Our furfriends can destroy a CD's data with application of a bit too much claw, but it takes a hoomin to make a device to read or transfer data that inadvertently destroys the material that data is on!

My CD will start when certain things come up. It's like the comp checks to see if the drive is needed. that could have triggered it.

Joel rushed >over to find it was coming from the computer, specifically from the CDrw [quoted text clipped - 8 lines] >commercial, high quality, expensive game on it, at that (Joel is Not Happy >at the loss of his game, which he hadn't even finished yet). See http://www.mythbustersfanclub.com/html/cell_phone_gas_station.html , which is a fan site for a Discovery Channel program that investigates various urban legends. The relevant experiment is described near the end of the page [each episode is two or three legends, and the CD thing was the third one in that episode]. >Can anyone offer an explanation, and whether its likely to happen again? As >it is, we don't want to put any CD in there that is important and can't be [quoted text clipped - 5 lines] >one of those things that is a freak of nature and is never likely to happen >again? As far as the Mythbusters could tell, a 52x CD drive *can* spin a disc fast enough to cause shattering. I want to say that they thought the quality of the CD itself was relevant, but since Bob doesn't remember that being mentioned in that episode, I'm not confident of that memory.

Bad Luck or just a spreader of CDRW sickness?...Last nite I decided to burn some tunes to listen to in the car(I had used up the last of my Imation one).....upon removing burnt cd...I found it WAS burnt! It had a small scortched, hole near the center of the cd...hubby thinks it was from it being a cheapie(thinner) cd with a defect in production(I got 100 of them for 7 cents per from Frys in Plano... Yes! Dave Y.! there's now a Frys in Plano...I no longer have to travel to the NW Freeway/Highway one! Burnt another one....quality was poor...went and got a $ cd bundle...tried again.....no burn...quality good......so...I think it WAS the "cheapie" cds.....now let's see if Frys will take them back! :-) Liz > Last night, there was suddenly an aweful noise from the kitchen.

Love the new Frys....it's has good sales(if you can get the stock before they sell out)...picked up a BTC 16X DVD-ROM Drive there last Friday on sale for $10!!!(you never know when a cat might "bless" the other one and fry it!!)....I'd already bought one the last sale for $17.99...needed on for the spare computer..... :-) Liz( see I got cats in the post!) > ":-)Liz" wrote: > > [quoted text clipped - 16 lines] > > Bob >What are you?

Off the top of my head I'd guesstimate two reasons - the CD drive was faulty, which can be checked by an expert (I don't suppose it's new enough to still have warranty left on it?), or the disc was faulty, had a manufacturing fault that made it "explode" at that particular time. If one would have the resources, one could check the fragments of the CD to see if it had a manufacturing flaw of some kind. But even if that was done, it won't get the CD back. Come to think of it, even if the CD drive doesn't have any warranty left, you might want to check either with the shop where it's been bought or the (representative of) the manufacturer, as busting a CD is not quite something that would happen to every CD drive.

CD was flaky, and the stress of the spin in a modern (48x, 64x) CD-Drive can and does make "stressed out" CDs break into pieces 2.) If the CD had something written on it, the ink may have contributed to tiny breaks in the CD - even before the data was lost 3.) Paper and similar glued to the disk stressed the CD and the drive 4.) As somebody already wrote in the thread, the CD may have come "unstuck" HTH Aleks Yowie had something important to tell us on Wed, 19 May 2004 07:49:28 +1000: >Last night, there was suddenly an aweful noise from the kitchen. Joel rushed >over to find it was coming from the computer, specifically from the CDrw Sometimes CDs explode... even expensive supposedly 'perfect' ones - nobodys' quality control is perfect. You could try gathering together all the pieces and sending them back to the games company with a complaint letter? Maybe you can get another copy of the game from them... but you'll definitely need a new CD drive - who knows what damage the flying CD shards have done to it :( SignatureKaren AKA Kajikit Here kitty kitty kitty... visit http://www.catslaves.org!
