I tried google and searching this site, didn't get very good answers.
I'm running 14.04.1 LTS. I have multiple 3.5" internal drives in my system with very important data on them. I'm only using one of them for ubuntu. I installed ubuntu hoping I could use it to play and mess around, without worrying about hurting the rest of my system.
In windows you can go to device manager, right click an internal drive, and click disable. Is there an equivalent in Ubuntu? I want it so that nothing can access the drives in any way until I manually re-enable them.
