Based upon my experience this week at the Family History Library in Salt Lake, I'm going to add a file on my flash drive, in the main directory.
I'm calling it--read me if found and saving it as a text file that can opened with virtually any word processor.
The file will contain my name, cell phone number, and email address. Then if my drive is lost and the finder is so inclined to open it, they should see the file. Of course information on the outside is good, too. But as we all know permanent marker isn't permanent and tags hooked to the flash drive become separated from it.
