said Leslie Turriff:

| 	Use lsof (list open files) to see what's making it busy, then umount?

problem was that the instant *anything* touched the removable device, it 
was automounted again. the solution was finding the item in the 
right-click menu that, when dived down to, would allow one to unclick the 
automount option. then it would stay unmounted. i discovered the option 
about 20 seconds after i hit send on the original question.

now comes changing the Q4OS version of trinity into the trinity version of 
trinity, and restoring all my settings. which will take a little while but 
will have to wait until i have a few hours to do it.
