I've tried this on an old drive (It had an old ESDI interface). I atached a fan, and once it got the power conector on, it would go full throtle.
But it would run hot and then some kind of embeebed termal protection would shut it down!! But for 40 seconds or so.... what a draft!!!:D
Thansk for the instr.

For example if too much pressure is used or damage occurs, the disk may explode and send shrapnel in many directions. Maiming and possibly killing people, pets or plants.
