No.
On a real operating system, the OS would simply notify userland, which
would do whatever it wanted to do. A sensible userland might then
spit out a dialog telling the user to put the disk in question back into
the machine, or it might ignore the frantic request from the kernel,
at which point the OS would return EYOULOSE to the poor process that
tried to access the no longer existing process.
