Hi Frank Cox!
You did remind me of a little problem possibly related. If I copy TO
a USB flash drive or MP3 player the operation goes fine (Gnome drag
and drop), if I delete from Gnome the item no longer shows up on the
device BUT the space is not freed. The way I get around it is a root
terminal to remove items on the USB device.
My guess on where to look: man hald, man automount.
Good hunting, I will be most interested in what you find.
