OT: Exploding CD's

Not auto-sim related, but I was wondering whether anyone had ever had a CD explode inside the CD-ROM drive? My mum bought Tomb Raider 5 this Christmas (Doncaster EB, UK), and the disk exploded inside her 48X Sony cd-rom drive. The drive wouldn't work afterwards so she bought another, a 52X (un-branded). EB replaced the TR5 cd, but tonight the same thing has happenned again. Luckily the new drive still works, but the second TR5 disk is now in a thousand pieces. Since there isn't a epedemic of CD's exploding with fast CD-ROM's, I can only guess it must be a batch of poor quality Tomb Raider 5 disks, maybe with hair-line cracks already in them. The stange this is that the first disk failure happenned after TR5 had been running for 1.5 hours, yet the second disk exploded after the PC had only been on for a few minutes and TR5 had only just been run. Can anyone shed any light on this topic for me? Thanks, Simon.

Yeah, I had a rented copy of LinksLS Disk #2 (for my SO's son on a visit from Yellowknife) explode in my Creative 52x CD-ROM. A -LARGE- bang...I jumped a foot and looked around for something the cats had broken...no sign. When I opened the drive a few minutes later, many tiny shards fell out!!! Toasted the drive. Creative and Microsoft both replaced the items involved. The drive was only 3 days in my machine. The replacement has been well behaved. The rental store was shocked...8^)...and passed the bag of pieces around. Said they'd never seen the like. J. P. Hovercraft Simon Brown wrote:

Is it a DVD disc? I've heard of this happening to DVD's.

Spinning at about 10000rpm, if my math is correct, the outer edge of the CD experiences a load equivalent to about 6720 g's (see http://www.sciam.com/1998/0198issue/0198amsci.html for formula). I'd put a Flack Jacket around that Baby! L. Willey "J. P.

I've never heard of this at all. When I read the original post, I thought you were setting us up for some joke. Sorta makes sense though, but this is a new one.

This is know to happen. It's also a reason you should never, never run a cracked disc, espcially if you have Laserdiscs. People have been killed by shattering laserdisc's in players. The velocity that these discs travel at can cause them to penetrate and exit the player- if you're standing too close, you could be hurt! Never, never run a disc you know to be cracked. Z.

If you do have discs that are cracked, you can get temporary help by freezing the disc in your kitchen freezer. This is a known trick in the audio CD community. Be sure to freeze them before every use just to be safe. +Cinquo

No, it's not a DVD, just a normal 52x cd-rom (the first one was 48x). I've done some searching around on the net and it appears that it's the disk manufacturers fault when this happens. Imperfections in the cheap plastic can make it very brittle when heated and cooled very quickly, hence the shattering. My mum is terrified to use the computer now :), and I'm glad i've still got an 8X in my own PC. "Regular Racer" <[email hidden]> wrote in message news:auw66.5143$[email hidden]... > Is it a DVD disc?

Since DVD discs are layered, it's easier for them to "explode". (Which I have seen, but only with DVDs). -Cheers!

But isn't the layer on DVD discs only a matter of terms, and physically a bit different ? As long as they don't grenade in my shiny new Harman/Kardon I'm happy :) -- Olav K.

24x's take a bit to spin up too. At least my Creative Labs one does. -- Chuck Kandler A man is no less a Slave just because he is allowed to choose a new Master every four years. Registered Linux User #180746 http://counter.li.org

I think 8x and up is where the long spin up times became common. dave henrie "FrenZy" <[email hidden]> wrote in message news:93i6m0$cu1$[email hidden]...

FYI, I was *joking*. In case someone hasn't noticed, this whole thread is baloney. Indeed a large number of people do believe in these things, which is utterly ridiculous. Remember the claims that a music CD's sound quality can be enhanced by coloring it with a felt-tip pen? Green-coloured pens were said to produce the best results... ;) +Cinquo +Cinquo

Yeah, you color the outside edge, and it reduces light leakage from the circumference of the disk. I remember when Stereophile was all atwitter about the little wooden trestles which propped up your speaker cables to reduce the capacitive interaction with the floor. Don McCorkle
