Edit: Apologies, I'm new here. One post, one problem. I'll put the first and hopefully most simple problem first and then leave the full issue below.
TLDR: What could cause an SSD to suddenly halve in capacity between reboots, including changing the model number the computer recognizes it by?
A bit longer:
I'll try my best to explain this but I feel I am surrounded by madness. How is this possible?
This morning I turned on my computer to a blackscreen and (to cut a long and hazy story short) after some attempts at fault finding I finally managed to get into windows. But.. it's the wrong windows. Indeed, according to everything including my bios, it's the wrong SSD. Somehow between reboots my SSD has halved capacity from 256 to 128, and swapped OS (including all the other files on the drive!) to--get this--not my last, recent install, but the one previous to that. My last windows installation was 64 bit.
The one sitting there now, including all files on the drive, belong to my 32-bit installation from over a year ago, from before I switched to 64-bit and made many hardware changes. I'm reasonably certain that my SSD back then was 128gb.. but I don't remember copying my entire drive over from that one. (And yes I physically checked, this is the 256 drive, despite what my BIOS and windows says; I actually lost the 128 a while ago) I must have done, unless there's something even more strange going on here, but that still doesn't explain this horrible magic trick. CHKDSK says everything is fine. Hah.
In summary: Overnight, with a powered down computer, I've lost half the capacity of my drive, all my documents and user files, and my windows installation, all replaced instead by a doppleganger that by all rights should have been long dead to overwriting. What could possibly have caused this series of madenning events!? If any of you brilliant people can offer help or insight it would be most appreciated.
