The page on which the spinup parameter is is on a vendor specific page if i recall correctly. So if you reference it in the /usr/share/misc/scsi_modes you might run into big troubles if some other disk vendor use the same page, for something entirely different, wich they might since its vendor specific. You could get your disk to agressivly not want to cooperate if you change the parameter on a disk which use the same page for something entirely different, couldn't you? regards/ Joakim
