OH, I would!
imagine your defusing a thermonuclear bomb...
now, CUT THE RED CABLE...
(but the HD should still be picked up when you do a soft reset though...)
the ide cable on the mobo should have the red stripe furthest away from RF output socket, (there`s a number `1` printed on mobo)...
And the red stripe on the ide cable entering the HD ,should be
closest to the power input
