I have nothing on the internal SD slot if that's what you're talking about. Unless you're talking about a different thing? I don't even have virtual memory on.

Every time i put a 4gb sdhc in my N800, it could never be recognized. It just said memory card corrupted and need to be repaired. If i tried to format it using the file manager, it would get stuck at the "Formatting memory card" bar for a while and the whole device stopped responding.

The whole application crash occurs even when there is no SD card at all on all slots.
