I had a SanDisk 2 GB Ultra II SD Plus USB card that got the axe in the external slot; my Adata 8 GB SDHC in the internal slot is fine. From the bug page and this thread, I gather that all SanDisk cards die horrible deaths with the N800. It's a pricey lesson.

I did really like the SD->USB ability, though. Does anyone have an SD card that can do this that also doesn't die in the N800?
