I have a DVD, a data DVD rather than movie or music, from Seagate Business 
Storage 2-bay NAS, that is mountable with mount_cd9660 but not readable in

ls /cdrom showed nothing; ls -al /cdrom showed

so it looked like something was there.

Mounted under Linux (System Rescue CD 4.3.0), main directory showed

Haiku R1Alpha4 ( was also able to show these directories and read 
the DVD.

Is there any way I can read this DVD in FreeBSD or NetBSD, or is this a 
deficiency or bug in FreeBSD and NetBSD?

I tried mount -t udf (no good) and "mount_cd9660 -be /dev/cd0 /cdrom" (same 
result as without -be).

What more details could I give?


You need to install sysutils/udfclient. Your cd is in UDF format, that isn't covered by standard mount_udf.
