Ok, so my hard drive in ACHI mode does not allow me to enable write caching but in compatibility mode it does.
Should I enable write caching?
Also this whole thing about memory loss is bugging me on what they are talking about. I have a laptop with a battery and mostly has power. But what if power were to cut off or it gets somehow unpluged, will my HD be corrupt? or would that "Word" document I was working on that was not saved be gone, everything else will be fine?
