What's the point though? It's not like you can plug that drive into anything other than the one PS3 it came out of. Why not just get a less expensive larger internal HD and swap it?
i read the largest 2.5 hard drive that fits is only 750gb (which is still a lot). I wouldn't mind using a computer instead of FTP also. i guess i was more thinking about external when posting my last post..
12.5mm HDDs (What some 1TB HDDs are) can fit if you don't use the cradle to house the drive. For a old console, I use dental floss as a handle to pull the drive out.
