 The .DS_Store is the desktop control file, not majorly important, but
important. The ._{string} file IS important - It's the resource fork
part of the file and MacOS gets a little upset if they go missing. It is
not a tempory file.
 Possibly in your case the resource file is not being written correctly
for some reason (hide dot files?), OSX is deciding that the resource
fork part of the file didn't write, aborting the copy and deleting the
otherwise sucessfully copied data fork as it 'backs out' the copy.

 OSX would probably be a lot happier with Samba 3 so that it can write
Unicode filenames....
