If the disks really were "on fire", my preferred means of shutdown was the big red button by the door as I exited, PDQ. Actually I did once have to do this. I was "minding the shop" at lunch time on a sunny day. As I looked into the machine room from the operations office I saw a cloud of smoke arising from the floor through one of the AC vents. Dead stop - building alarm and get out. It turned out that one of the AC units had started its steam generator and the blast was picking up dist mites, which showed up in a shaft of sunshine looking light smoke.<insert red face icon> Most machines were at the far end of the room and it was only occasionally that that particular unit came on. The fire brigade confirmed that it was the right action, but some of the users were less happy! -- J Martin Rushton MBCS
