I recently restarted my computer I built, and went to look at my documents on my ssd and they were all gone, alond with my ssd not showing up at all. Along with that, it looks like the os is now on my external hard drive, and the memory 232 GB instead of its actual 2 TB. I don't know what to do, I'm new at this whole built computer thing, and am afraid I might mess it up somehow, if I haven't already. Anyone have some help or advice for me? Has this ever happened to anyone else?
