You work with computers long enough you'll see everything.
Cleaning office. Stack of cd-roms; maybe 8+ years old or so. Do I need them? Lets take a look whats on these things...
And now I can add "cd-rom exploding inside dvd-rom drive" to the list of entertaining computer events I've experienced.
Silver flakes and plastic shards everywhere. Had to use a garden trowel to wedge out some pieces that got stuck at a 90 degree angle deep inside the drive. Surprisingly, the drive is fine - at least reading; not sure I'll trust it for burning though...
Why did it go explodey? No idea...
