Excellent answer, Fred. Might I also suggest that if it is a problem in the
transfer (which is what it sounds like), you might use ssh to make sure the
transfer is clean. You don't need the encrypted link, but it does checksum
verification that a cp doesn't. Try using

scp <insert files here> localhost:/mnt/archos
