Afternoon all, I'm looking at upgrading my 80GB hard-drive to a 320GB (but this thread isn't really about that). I haven't got any external storage I can use to do a full back up of my old data so was looking at my system to see what stuff I do need to back up - which is only really game saves. I have no music, videos, pics etc. Now as I'm sure your all aware, game saves take up relatively little space on the hard-drive and as such I will transfer most of them to a memory stick while I replace the hard-drives. Now to the point What exactly is taking up all the space on my Hard-Drive? It is 72GB full and all I have are the aforementioned game saves, no video, no music, no pics. Yes I have about 8 demos but if I take these off it will still only free up about 10 more GB tops. So what's stored on approx 55GB of my PS3? Software updates are often very small (the last Fifa update was only about 32MB I think). When a new update comes out and your system updates it - does the PS3 automtatically delete the old software update or is this still saved somewhere? Why do I need to update my hard-drive when I don't even know what's filling my current one!!??
