Yesterday my main hard drive started acting up, my laptop stuttering and freezing. sfc says everything’s OK but chkdsk keeps stopping with an error in Stage 3 I think it was. My laptop has two hard drives – the SSD one (which I upgraded maybe 4 years ago) with the operating system and all my programs and as far as I can tell is working great, but this other one, now troublesome, is the one with all my stuff on it and it’s old, so it may just be dying.
