hopefully my question is simple but it is still worth 500 points to me. anyway i have a laptop with 2 different hard drives in it. i use one for the operating system and then one to put data files on that i want to keep. is there a way to turn off the power to that second hard drive to help save on battery life?

More info needed like what laptop for starters

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.


it is an hp pavillion dv8100 model number es184av


if i disable the hdd in hardware manager will it turn off the power to the hdd?

of course- that is what you are asking


disabling it in device manager did not turn the power off to the drive
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.
