Finder.dat is a file the (pre-OS X) Finder creates on MS-DOS formatted drives (or a few other "foreign" formats) to hold the Finder information that's usually stored on the Macintosh filesystem. That includes the desktop database and the file metainformation (creator codes etc.) You can ignore that file. If you throw it out, Icon positions etc. will be reset but nothing terribly bad will happen. (You should use MS-DOS style file extensions then, because you'll lose creator/type information.) You can also reformat the drive using HFS/HFS+, which will get rid of Finder.dat altogether, but will make the disk unreadable on Windows. AFAIK, there's no way to tell the Finder not to (re)create this file on an MS-DOS partition it writes.
