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.

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!

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.

I'm gonna get one of those welding masks and wear it from now on.........

Holy ***!!!!!!!

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.

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.

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.

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

Very interesting. 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 :)

I've never frozen a disc, but I can tell you what happens to an AOL cd when
you stick it in the microwave ;)

I'm glad i've still got

Excuse me for going off the off topic topic... But at what speed do cd
drives start to have long spin-up periods? My ancient 4x drive accesses
files and directories almost instantaneously where the 32x drives I've had
spent up to 5 seconds spinning up.
