titan# mount -t cd9660 /dev/cd0a /mount cd9660: /dev/cd0a: Invalid argument the exact same issue. reinstalling etc is not an option since this is a development machine and i need to work on it all the time, can't afford for it to be down. fyi i am using freebsd 4.10 release is there a way i can delete /dev/acd0* and remake the device, could this be a fix?
