It is possible to enable, or to change the power save settings of the second HDD drive. It will be able to go to power save mode, wchich could be as good as power off.
Advanced hdd settings software is necesary to do so. Each HDD manufacturer has own software needed in such a case.

check in the bios for a power option for the disk drives.

Give this a try.

•  Whenever possible, adjust power management settings (power schemes) in Control Panel to permit
the hard drive to be turned off when it will be unused for an extended period of time, e.g., when
you are working in applications such as a word processor that executes primarily from electronic
memory without having to access the hard drive very often.

"... if i disable the hdd in hardware manager will it turn off the power to the hdd? " ==> No.  Disabling a drive not only disables it, but also disables all power options associated with it;  so the drive will simply "spin away".

The best thing to do is just go into your Power options menu and set a very short interval for turning off the hard disks (say 1 or 2 minutes).   This will set BOTH disks to turn off after that interval -- but if you access one (say the primary disk), ONLY that one will spin back up ==> the other won't spin up until it is accessed.   I assume you know how to do this ... but just in case:  right-click on the desktop;  select Properties;  click on the Screen Saver tab;  click on the Power button;  now just set the "Turn off hard disks" time to whatever you want ...
