It's been snowing and freezing for some days now - I think that's pretty early.
On another note, one of my HDDs just vanished. Or at least its partitions partitions did. Among them were my Ubuntu Boot Partition (containing GRUB things) and a general data partition (containing amongst others my music, documents and programming stuff). I'll later write a full image of it before trying any recovery.
I just changed my pc case and added a new 2TB HDD, I don't think that's connected to my problems though.
Note that this has no influence on my current write-the-first-comment-competition.
