I pressed shift-delete. I did not move the files to the trash. Nor are
there any .files on the drive, so there is no .Trash file on the
drive. At least, not that I can see in Konqueror or Konsole (-a

That is what I always do when removing files from removable media.

I do not see a .Trash file in either Ubuntu machine (even when looking
at .files or hidden files) nor on the DVD player (with USB input).
