Hmmm.... The 1394 connection was bound to Client for Microsoft Windows, 
Service Advertising Protocol, File and Printer Sharing for MS Networks, and 
Internet protocol.

I don't anticipate using the 1394 connection for anything soon, so I 
cleared the checkboxes for most of that. SAP is greyed-out, can't change 
that one.

My first attempt to copy files to a samba drive failed immediately, just as 
before. Perhaps a therapeutic reboot is necessary.
