CD Exploading.

drunkbum222 · 12-16-2007, 02:07 PM

Now I for one didn't think it was possible at a normal drive speed but yesterday it happened. I was at my friends house playing games when we all just suddenly hear a loud pop. At first I thought his memory just arched or something because he started to lag severely before it went to his desktop, but I knew it couldn't have been that.
He restarted his computer and everything ran fine, He then went back to playing Starcraft, but it couldn't detect the CD in the drive. So he opens it up and to my surprise the CD was shattered into several pieces.
He has a normal CD drive with a normal CD, so I didn't think this could happen. What would cause a drive to reach such intense RPM speeds that it would shatter a CD.

P.S. There was nothing wrong with the cd.

Nothing wrong? How about a disk that got brittle! That would explain it being found in pieces especially if the disk got cold from being outside depending on your location was heated too fast when placed in the drive. If no other disks have problems in the same drive that would be the likely cause there.

The lazer lens would have then acted like a microwave when warming a cold disk. Or some flaw in the disk's material was revealed. That just turned out to be the final straw if nothing is found wrong with the drive itself.

happened to me awhile back, its too bad that manufacturers cant simply make a stronger product, if we have to watch how cold it was right before sticking it in the drive then scew cd's, im going to flash drives they dont explode

If you are in a regoin that sees frigid temps from winter weather and carry disks with you or leave them on a car seat they get cold fast. After a period of time the material will get flexed back and forth from cold to room temp to cold again. That will make any vinyl or plastic type material brittle.

The same in some sense would be seen if leaving a cd in car during warm weather too. It's just a matter of physical science there. For those that drive leaving even their audio cds in the car with sunlight bearing down on them know that one! It's sad to see it happen but being smart can save a few headaches.

Hey did this appear on mythbusters?

Season 1 Episode 2

According to wikipedia, it was "plausible" in the actual episode, but was called "busted" in future episodes. Maybe we should demand a myth revisit!

Anything spun above 50,000RPMs can be destroyed. This included steel bearings, cds.. engines.. I know its high, but wanted to point it out..

a 48x speed drive will go to 24000RPM's

Mythbusters went back and tested it again and decided after further review it wasnt possible under their conditions but they did admint that under the right cercomstances it could happen aka in what pc-eye is saying...

I got this computer from someone. The drive worked fine, but I kept getting pieces out of it. The owner told me a disk had exploded in there a while back. Well eventually the drive quit ejecting so I took it apart to clean it out. I'm not exactly sure of the speeds here, but I suspect it's only a 32x or something around that. It's from an older P4 1.4GHz Gateway computer.

Speaking of microwaves and CD's... anyone ever stick a CD in a microwave for about 10 seconds? You hafta actually turn the microwave on though, don't just stick the CD in there for 10 seconds and expect something to happen. =D

I know that's not what you meant by microwave but it just made me think of it.
