From the burncd manpage
-m close disk in multisession mode (otherwise disk is closed
as singlesession).

one thing that we forgot to mention, is that if we use burncd with the
fixate option, at the end of the write (both when using -t to test and
when doing a real write), we get an IO error (something about
IOCLOSECD). If we don't use fixate, we don't get the error, but then
the CD won't mount anywhere either.
Attempting to mount a cd after writing it has caused page faults and
subsequent reboots on all three attempts now.
