I've got 2 512 samsung cards, I tried both of them. I tried to format them with the N800, I thought that might be the issue, but it seems like anytime any card I put it in is accessed through either slot, it hangs. I tried reflashing to 2008 beta, no difference, then back to 2007, still doing the same thing. I am going to try reformatting on my computer and see if that helps. Thanks alot for the quick replies!
