Ever had a cd or dvd that exploded ? Well believe it or not it can,under certain conditions happen, luckily only when the disc is in the cd/dvd drive !

What happens?

You will first hear a nasty bang followed almost immediatley by the most awfull grinding noise. The disc will have disintergrated into thousands of tiny bits and ruined your drive. This will have to be replaced. Shards of the disk will not come out of the drive, they are built to prevent this.


The most likely time is when copying the disc at speeds of 40x or more. In play mode a cd revolves at 200 rpm, when copying at 52x this increases to 10,000 rpm or put another way 180 mph. At these sort of speeds the disk actually distorts, should the disk have a small crack on its inner rim.....well I think you're getting the picture.

Why it can happen

First a small crack will appear on the edge of the inner hole, this over a period of time will get bigger until eventually B A N G !


Moral of the story

When copying a disk keep the speed down, yes it takes longer to copy BUT in the long term may well avoid a ruined drive.

Before playing you disc inspect it for any signs of cracks on the rim of the inner hole. Discard the disc if you see any, order another disc from e-bay. Best be safe than sorry. If a cd or dvd should jump tracks during play or copy mode it may indicate a crack, stop immediatley and inspect the disc. Be wary of borrowed or second hand disc's always check for cracks.


Never put sticky labels on your discs. Over a period of time they will lead to problems. The 'all over' (full circle) labels may be better, but I prefer to play safe and avoid. Imagine one of these labels becoming unstuck while the disc is revolving at speed. Most of us are aware that video labels sometimes come unstuck after a prolonged use. Video's are one thing, high rev discs are another, thats why I avoid such labels.

So enjoy your cd/dvd and hope they provide cracking good entertainment, rather than cracking dissapointment.
