let me see if i can help a bit, since i got a ps3 awhile back and have played with it a bit as well. The 7 gigs of space that is taken up is the playstation Operating System...aka....OS. No way to get that hard drive space back. In respect to adding memory cards and what not...you can get any kind of memory card ya like and use that for additional storage i have a couple of 2 gig flash drives that i use to save and load up games, video, pictures, and music to and from the PS3. You just have to make sure you have the memory card or flash drive set up properly so that the ps3 will acknowledge whats on there....if ya need anymore help...please let me know....i will do what i can....take care,Tommy
