Regarding the HDD failure sounds. A shame I could not have recorded this but I came across an IBM XT 20mb HDD (yes, you read that right, an IBM XT twenty megabyte hard drive, this was about circa 1991 lol) Anyways, it would not spin. So my coworker put a tiny amount of some oil on the bearing and lo and behold it started to spin. Then came the sound....literally sounded like a banjo. Boing-boing-BOING!! (the sound of the head arm actuators smashing up and down againsed two of the platters, one top, one bottom). We laughed so hard we almost fell out of our chairs. Too funny.
