FUCK. MY. ASS. I had about 2 more gigs that I needed to free up, right? So I went through my save data and starting deleting everything that wasn't nailed down, basically. Any games I didn't own anymore, stuff I didn't need, like extra Fallout saves, stuff like that. I must've had about 500mb to go or something. Then I realized that I still had Playstation Home installed. It was over 3 gigs.
Anyway, yeah, I got my PS3 back in 2008 or something, so 40 gig was one of the only sizes and it cost quite a lot. I don't wanna drop the money on a new hard drive, because if I do, the next day my PS3 will die and I'll have to either fix it or get a new one anyway. And if I'm really lucky, I can just wait long enough and get a PS4. Although I doubt that'll happen.
