My computer just exploded...!
Discussion
I have just been browsing some old pictures and movies I have written to CD when there was a huge BANG from my 'putah. I stopped everything and when I ejected the CD it had EXPLODED inside the drive...! Bits of plastic and foil fell out everywhere.
I seem to have fixed the drive - disassembled it and cleaned it all out and it's working again. So much for the CD though - it's very dead. Only downloaded crap on it, but even still, could have been one of my digi photo discs...! Double back up everyone...!
Aparrently if you get a hairline crack in a disc this can happen. Check your discs before inserting them everyone (yes, I said DISCS
)
It's a 52x Samsung CD-RW drive, so I guess when in spun up to speed the disc let go.

After todays events I'm tripple backing everything up!
It is to do with the crack and the speed the drives spin at btw, there was a huge annoucement a while back (about 3 years now) and stickers were sent out by suppliers in warning. It was all to do with the onslaught of faster CD drives into standard PC's that this had become evident, previously the spinning speed wasn't fast enough

D'ya know why CD drives haven't gotten any faster than 52x? Because after that spindle speed (which only occurs for a split second when the read laser it at the extreme outer edge of the disc - it can only handle about 20x on the inner edge) nobody has been able to make a consistently reliable CD that doesn't shatter! Also, the polycarbonate that CDs are made of also can deform at very high read speeds, further solidifying the curretn 52x limit.
At 52x, your disc is spinning somewhere in the region of 25000 to 30000 RPM - i.e. FAST!!
So don't be surprised when one decides to give way and you're left with shrapnel - just feel sorry for those guys with slot-loading drives as opposed to caddied ones like most of us.

having watched mythbusters on this very subject the only way they could accurately reproduce this problem was by spinning the cd's on a router at 3 times it's normal operating speed, akin to something like 300x on the cd's that were verified to 52x whereas on the cheap ones the margin was much higher for explosions/destruction
