How will my computer know what directories to attach the drive to? - Jason Saint Aardvark the Carpeted wrote: >Jason Dusek disturbed my sleep to write: > > >> 5 # mount /dev/acd0 /cdrom >> mount: /dev/acd0: Input/output error >> >> > >You may want to try: > > mount -t cd9660 /dev/acd0c /cdrom > >or its equivalent: > > mount_cd9660 /dev/acd0c /cdrom > >Also, if you're trying to mount a DVD instead of a CD, you may need to >try: > > mount_cd9660 /dev/cd0c /cdrom > > > >>I have some another disk mounting question, too.

It might mean that you've specified the wrong filesystem -- >"mount" (which defaults to FreeBSD's UFS filesystem) instead of "mount >-t cd9660", say.
