Hard Drive Spin Down issue

my 3x1tb drives are quite loud (7200rpm) and id like to spin them down, windows never does this, but using a program called hdd scan i spin them down manually, the only issue is that if a program needs to write do a drive the drives dont spin up, this fills up the ram and then locks up the system, the drives dont spin up until i manually press spin up on hdd scan, im lead to believe that its my drives firmware as the 750gb laptop drive in my computer spins down using the program and spins up again if data is accesed, if a program tries to read the spun down drives then that program crashes, not the whole computer. Anyone know why this is happening and if you have the same HDD as me do u have the same issue (Western Digital Blue 1tb 3.5Inch 7200rpm)

 

windows does spin my drives down without any tools...

Go into the advanced power settings and there is a setting for whether a drive can be shut down when inactive or not.

 

Yeah, but it just doesn't, I have the task manager on and no drives have activity, and they don't power down, my 5400rpm drive does, that's an apple drive, my 3 WD 1tb drives just stay on the whole time, and so get hot 40-50C if I switch it off using a tool then it won't come on when something is read or written, so it just freezes that process, if it is writing then normally it will fill up the memory, and then freezes Windows as it can't flush the cache.

 

did you change the setting in power management.

apple don't make drives either, they use Hitachi ones, crap ones.
