HeresMyAccount: Coincidentally, I
finally got around to fixing it just last night! I did have to reinstall Windows after all, but that's interesting information to keep in mind for the future
You bastard! After all this time you're letting us hang like that... :p /s
But technically, if you needed to reinstall Windows you didn't actually fix it?
Digressing; In Norway we have something called the "Swedish button", which is to shutdown via the power button by holding it in a few seconds. This increases the likelihood of corruptions, but it was worse back in the day. Which can be prevented by disabling some of the disk write cache on a disk.

While disk write caching may increase system performance, it can also increase the chances of data loss in case of power or system failures before the data from the write-cache buffer is flushed by writing the data to the disk.
(Don't ask me why it's called that way. Norwegians and Swedish have always had this "little brother" syndrome thing going on. It's probably because Norway is quite "young" and had to exist under Sweden for so long. idk.)
