the clicking is a parking feature to preserve battery life
i use the program ‘cause it feels weird hearing a click click every so often. it’s annoying and noisy.
and about preserving battery life? i don’t see a change. my computer dies in 4 hrs with it on or off.
silentdrive is on the board or google. if you still can’t find it, i’ll post it up.
btw. hitachi offers a hd program that can actually turn this feature off. browse on their website. unfortunately toshiba doesn’t offer it
