The journal will generally cause quite a bit more writes onto your USB device. I use ext2 on my CF card in my NAS for that reason (the spinning media is on XFS of course). I know that's not an answer to your problem but thought I would add it as a suggestion :) Tim -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
