It was burned probably by a MRI scanner operator station directly in a way that mount_udf (nor mount_cd9660) could not mount it. macOS also could not open the disk. Windoze 10 opened it with no problem. I was able to DD disk with no problem for investigation. Disk does not seem to have valid ISO signature (hybrid ISO+UDF). Is there any chance that this is the ISO+UDF disk but FreeBSD does not support modern UDF versions? Maybe some sort of raw UDF disk? Dmesg error message: Unsupported partition map: *UDF Virtual Partition Looking around I found a forum thread that suggested 7Z could extract iso/udf files.. but that does not work either here. ISOINFO does not seem to recognize that disk either: hexagon% isoinfo -d -i disk.iso Setting input-charset to 'UTF-8' from locale. **BAD RRVERSION (67) in ' ' field 09 18.
