Hi Again, In that there must be something else wrong, because after trying a few permutations I was unable to get the drive on my D600 to work: 1 root # mount_cd9660 /dev/acd0 /cdrom mount_cd9660: /dev/acd0: Input/output error 2 root # mount_cd9660 /dev/acd0c /cdrom mount_cd9660: /dev/acd0c: No such file or directory 3 root # mount_cd9660 /dev/cd0c /cdrom mount_cd9660: /dev/cd0c: No such file or directory 4 root # mount_cd9660 /dev/cd0 /cdrom mount_cd9660: /dev/cd0: No such file or directory Do I need to create some directories for this to work? 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.
