I just do the same checks that we do on boot. I suppose if somebody does
this with a mounted filesystem on removeable media the results might be
rather comical...
Does "Medium May Have Changed" show up reliably if somebody changes the
medium in a cartridge drive, Zip drive, etc while it is powered down?
Doesn't the kernel already notice that sense if it happens during normal
operation?
