yes, i assumed that the poster wanted to detect an unclean removal of the
media.  obvious ba? kaya nga may pa-sticker-sticker pa ako eh.

at least si dido gave me bit more credit. =)

now, if the poster wanted to know if somebody unmounted, and then removed
the media, then that's even heaven of a lot easier to detect using
userland tools and kernel debug output (you need a kernel patch to output
mount/umount syscalls to syslog)
