Im installing a bunch of stuff and wanted to know how much room i'd need to leave on E to have enough room for the save games for the XBOX games?

You should leave at least a couple hundred megs. I always try leave around a gig, just to be safe.

If you add too much on E you will run into errors all over the place, but if you have a seagate hard drive you can format the f partition and gain 2 more gb

thats only with the seagate drive? I kept stock HD in mine and I cant eve access the F Drive. So Im putting everything on the E drive. (emulators, roms) If I almost fill the E drive this gunna cause a problem if I dont backup Xbox games onto the HD?

Well, if you got Seagate hdd and you can't access the F drive it's because you never formatted F Also, you may want to change your signature, the admins/moderators may find it bothersome and will cause you harrassment further down the road in here
