Hi!
I've made a small utility so one can set the spindown times on IDE
drives. Works great for me. I hope this helps those who wishes to keep
the drives quiet. I start it in autoexec.bat. I guess most people have
this functionality in their BIOS's. Well, my old computer don't have it.
:-/
Please take a look at the source, maybe I'm doing something wrong, I'm
not an expert coding IDE hardware.
regards, Tommy Hallgren(md6tommy@mdstud.chalmers.se)
