You can use any of the old 360 hdd's on your slim to alleviate the problem. Kinda sucks but its the only workaround I know as of now. This only affect online co-op btw, not split screen co-op.

Here's a post explaining how to add a fat 360 hdd to your slim

Thanks a lot. I'm going to do this for a friend of mine that just purchased a 360S Arcade. I can use one of my old 20Gb HDDs or buy a used 60Gb or something.

As for the OP I noticed that on the 4Gb models, when you go to system settings and look at the storage it doesn't show the Microsoft logo for the 4gigs. It shows it like it's a memory stick or flash drive.
