I have a 750GB drive which is ONLY used for Piracy. Not organized at all.
As for my Windows drive, I have a bunch of images and music I've saved from other sites, totally unorganized as well.
In fact, the images aren't even named. It's hell to deal with this. But I have at least a thousand of images (literally), so it's not very easy to organize them.
I guess I have basic organization for image and music, since I put them in My Pictures and My Music, but it ends there.
