That image mounts and works fine here. It was powered down half-way through 
an erase operation @0x40000, so we have an entire 128Kb of dirty flash, but 
it handles that just fine.

Which file do you think is missing? "jffs-testfiles/8"?
Remember that cp(1) will unlink the file before creating the new one.
