Our transition from Windows 2000 to XP
came about because, although the W2000 installation CD had a visible hairline crack, it hadn't, hitherto, inhibited successful installation.
However, this day, the cd span at ever higher speed, with a juddering overtone. The volume of speeding cd drive and juddering rose until there was a shockingly loud noise like a gunshot, and suddenly the room was filled with pungent dust. The installation CD was history, and so was the drive. PC perfectly happy.
