I replaced my main laptop hard drive with a 240GB SSD. Ordered one of the faux optical drives that allow you store a second hard drive where your CD-ROM use to be. I'm able to access both drives successfully, my only problem - the battery life is literally about a 1/2 or a 1/3 of what it use to be before this new hard drive arrangement.

I'd read forum posts about the old Ubuntu bug where it can continuously cycle your drives. I am not accessing this drive. Not reading or indexing the data on it. It is my Windows 7 NTFS drive that came with the system. I was going to format it and use it as additional storage but now I'm debating just putting my optical drive back in.

I could understand if the battery life diminished slightly but if I'm not actually moving or using the drive AT ALL. Why does it affect life so much? Is there a way to correct it or possibly leave it completely unmounted unless otherwise needed? Thank you in advance.

Rather than removing the drive entirely, which would certainly work, why don't you set some energy saving settings like the ones suggested here .

In Disks select the drive and click More Actions then Standby Now, although you will have to do this every time you start the computer.

Alternatively you I think you could edit fstab and have the drive not mount, but thats for another poster to answer.

user142712, I went to the Disks section and was able to turn off automount. I also saw the option to Standby Now. I'll look into automatically running that command after login if I don't see the desired results. I'll be testing it tonight for several hours and will report back.

Jason, I will also try spinning down the disks to see if I can get more performance from my battery. Thank you both.
