I've had one CD-R shatter and the drive was indeed unusable after that.
I tried to repair it, but after an hour of clearing bits out and putting
the thing back together, testing, dismantling, rinse, lather, repeat
I decided it wasn't worth the hassle. I still have it in case I
run out of CD drives in some far distant future ...



One of the last projects we did at Philips US, was a study to see how fast
we could spin the disk before it shattered.  A friend of mine, a mechanical
engineer, did the testing.  He had a blast.  It was like a mini version of
Mythbusters.  Even had the high speed television camera.

To accelerate the process he would often nick or chip the edge of the inner
hole.  When they split - literally - it was right through the front door of
the drive.  He finally got his own lab so the rest of us would feel safer.
But what a fun job he had!  He loved his work.
