Can't mount any cdroms: bad superblock: OS was installed from same drive!!

Odd!

Anytime I try to mount my cdrom /dev/acd0a on /cdrom: I get a bad superblock
error with FreeBSD cd!!!

Oddly enough, I used this cd to install the OS!

Any thoughts oh great gurus?

If you do something like
mount /dev/acd0c /cdrom

then the system assumes that you have an FFS filesystem on /dev/acd0c.
So you have to use an option like

mount -t cd9660 /dev/acd0c /cdrom

But normally, if you installed from /dev/acd0c, FreeBSD creates an
entry in /etc/fstab like this:

/dev/acd0c              /cdrom          cd9660  ro,noauto       0       0

In that case, it is sufficient to enter
mount /cdrom

Yes, but with a bunch of additions to make it go much, much faster.

You probably need to tell it that it is a iso9660 filesystem:

        mount -t cd9660 /dev/acd0a /mnt

No guru here but I do recall seeing that error when I had screwed
up the command for mounting.

Would you care to share with the exact command line you have used?
