All of a sudden, I get Filesystem error when inserting a MircoSD into the Gateway. I thought it might be a contacts issue, as the card looks elevated in the device, but I tried using paper/tape and it didn't work (I might be doing it wrong though). If no SD card is in, I simply get read error, so it must be detecting the card to some extent. I tried this with 2 mirco sds, and happened after I was using it with an old Micro SD. Diagnostic test shows fail on SD test. Fortunately I have BBM installed and my EmuNand backed up, but I'm annoyed by the fact that I won't be able to use .3ds homebrew. I got mine a RHS, so returning it for a new one is out of the question.
