Is it possible to change the power settings specific to 1 drive only

Assuming I am using the correct terminology in my question but knowing that I am possibly talking about something else I will explain. Having done a fresh install of Win7 HomePrem I noticed that when I click on a drive I have to wake it up--it doesn't open immediately and I could here it begin to hum. Prior to my reinstalletion I did not have to do this--clicking on any drive would pop up a window immediately. Then I recalled that I had done this manually and I think it was through the 'Power Options' --> Advanced Settings --> Hard Disk --> Turn off hard disks after... Am I correct in this? That this is how I prevent my disk from going to sleep/turning off? by setting it at 0 or 999 minutes. Assuming not then how do I do so. Assuming yes, then is there a way to do so only for one HD? I have 4 (where my OS sits and 3 others). I do not like to wait every time I want to open a folder in a drive I am not presently using and since this drive mainly happens to be the D: drive and not my E: or F: drive (hardly used) I was hoping I could be specific.

Does the registry control hardware? Maybe the answer lies there. If not then how does one turn it off completely. I don't recall.

whs: thanks for your help It seems that 15 months is too old for this case. And by this I mean the info on the link was created 15 months ago and it seems to no longer apply. On it, it shows a photo stating "turn off hard disks : never" and the 'never' option no longer exists--only numbers, representing minutes, are given as an option hence why I was wondering if I had done something else the 1st time around. Also it shows steps that are not necessary: Why create your own named power plan since it can be done so without creating your own but by simply choosing what Windows has to offer?

As mentioned mine is a fresh install which may mean 3 things: -1- your ''older'' install allowed it but a newer one does not or -2- You have done something to your system which allows you to do this now (but you can't recall what it was) -3-I have hardware that you don't have which somehow changes the power options (This may be possible since my PC is connected to an external battery source--which is then connected to the wall--but I don't see as to why this should effect the hard drives).

No, It's a PC but as I said. It is not directly connected to the wall, it is connected to a battery like thing (''HID UPS Battery'' According to ''Devices & Printers"). It is something that does 2 things: it regulates the electricity going in it--so that it is constant (A home's electrical power is never 100% constant) and it has a battery should there be a power shortage. This HID UPS is also connected to the PC via a USB.
Having said this, I may be wrong here, but if memory serves me right there was an option like your before my reinstall. The HID was installed after my initial installation of Windows. So this is the first time windows gets installed with that already a part of it.
