    Thanks, Peter. That did the trick.

    But I'm only getting data back from my internal drive; my external USB drive
    doesn't show up in the queries. Do I need to do something special to get
    information back from the external drive?

    Also: can you recommend a good reference for me to read that might explain
    this stuff at a very basic level? I've found some isolated examples, but
    nothing that actually explains the "big picture".

    Thanks,

    Jesse
