Can we do something about atime on removable media? It is
non-intuitive to most users that sticking a drive in and copying a
couple files off from it is going to cause writes to the device. A
normal user would think that this is read-only access and it is ok to
yank the drive.  I've burnt myself several times from this.

Another thing that gets normal users is yanking out a drive that was
definitely idle and then not having the icon for the drive disappear
on the desktop.

Maybe change distro mount defaults for removable media to noatime? And
add an event when the drive is yanked with no pending writes to tell
the desktop the drive is gone?

Of course yanking with writes pending should generate a big error box.
Can it ask the user to reinsert the drive and pick up where it left
off?
