I suspect the problem is this: some USB devices are formatted like hard drives,
with a partition table at the beginning, then 1 or more partitions to follow.
But other USB devices are formatted like floppies, where the partition occupies
the entire drive, and there is no partition table.
At a guess, I'd say yours is formatted the second way. Try "mount /dev/sda /tmp/flash"
