I've a Blue Ray DVD drive BH14NS40 that refuses to read any disk unless it is booted with a disk in the drive. Doesn't matter, if there is not a disk in the drive when booted it will not read any disk at all.......is this a copyright in the firmware thingy??? It has the latest firmware and if booted with a disk in the drive it will read disks without issue........It is just an annoyance ....anyone else have this anomaly ?
