I worked in a mainframe shop that replaced their removable media with fixed
drives. One of the stories was how, one day, after they loaded the removable
media, the heads crashed. The guy said it was the neatest thing to actually
watch - the covers were smoked plastic, some sort of noise, then the covers
were suddenly white.
I have a 3380 HDA I saved from my mainframe days...had a MAJOR
headcrash....when I opened up the top to look, the
head that crashed was vaporized!
