There are stupid things, and there are stupid things.
I did something stupid. (like I've never done this before!!)
I accidentally managed to make a few partitions of my HD disappear. That's not good is it?
The one containing all my music, and also the one containing all the Friends episodes that I had, and I mean all the episodes!
Sheesh! This is going to take a while to recover, thanks to limited speed of disk access. But then quantity comes with a tradeoff against performance. Like a big healthy person, more intake, less speed!
