Here are a couple of items that need to be updated in the documentation. Thanks!

1.) Make the reference to the tape name/number/id/serial consistent across all documentation.

2.) In the "Writing to LTO" section, the command should be updated (you are not prompted to do anything when just running "writelto"):
writelto -t ${tapeserial} /Volumes/${sourcedirectory}

substitute machine dependent datatypes like int with fixed ones like u_int64_t
This is not difficult but we should have some tests first.
