Problems Mounting a CD (solved)

[Victor Gregorio]

Ok, so the problem was with the starting sector.  By default, the sector 
was 15112.

root:/# mount_cd9660 -v /dev/acd0 /mnt
using starting sector 15112
mount_cd9660: /dev/acd0: Invalid argument

If I changed the starting sector to 0, I saw the fs but no folders.  I 
had to use -s 14660.  I was able to get "14660" from cdcontrol....

cdcontrol> info
Starting track = 1, ending track = 3, TOC size = 34 bytes
track     start  duration   block  length   type
-------------------------------------------------
     1   0:02.00   3:15.35       0   14660   data
     2   3:17.35   0:06.02   14660     452   data
     3   3:23.37  11:02.37   15112   49687   data
   170  14:25.74         -   64799       -      -

Solution:
root:/# mount_cd9660 -v -s 14660 /dev/acd0 /mnt

Just figured I'd post the solution since I had seen this question asked 
in a few freebsd.org mailing lists.
