P.S. BD-RE with UFS is the same result (not usable).
1. format the disk
dvd+rw-format is failed but after this step the disk is
newfs-able.
# diskinfo -v /dev/acd0
/dev/acd0
2048 # sectorsize
8796093020160 # mediasize in bytes (8.0T)
4294967295 # mediasize in sectors
# kldload atapicam
# dvd+rw-format /dev/cd0
# kldunload atapicam
# diskinfo -v /dev/acd0
/dev/acd0
2048 # sectorsize
24220008448 # mediasize in bytes (23G)
11826176 # mediasize in sectors
2. newfs
# newfs /dev/acd0
the following message was detected:
kernel: acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05
3. glabel and mount
but the disk access frequently failed with these messages
(offset and length is not always the same):
kernel: acd0: FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05
kernel: g_vfs_done():label/DailyBackup[READ(offset=2697789440, length=16384)]error = 5
