BDRE mounted read only

Got a PC with an ASUS BW-16D1HT blue ray writer, that is capable to read/write BDRE media. Bought a set of Verbatim BD-RE25 disks, formatted them under Win7 to UDF2.5, and tried to mount them under ASCII amd64, latest backports kernel 4.19.bpo5. I always get:

# mount -t udf -o rw,noatime,async,users /dev/sr0 /media/DVDRAM
mount: /dev/sr0 is write-protected, mounting read-only

Formatting/writing a new UDF2.5 file system under ASCII works, but does not change the behaviour. udftools are installed.

Any suggestions?

Thanks, Rolf

Re: BDRE mounted read only

Addition: Mate shows a popup telling me:

Error mounting system-managed device /dev/sr0: command-line "mount"/Media/cdrom0" exitet with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sr0, missing code page or helper program, or other error. 

There is a hint to look into syslog, or dmesg, but there is no entry present.

Writing under Win7 works.

Re: BDRE mounted read only

Usually, when I get a message like that (mounting a file system goes haywire), it can be resolved by running fsck on the partition:

fsck /dev/sdX1

My experience is that the drive behaves perfectly fine afterwards, but these are hard-drives, not removable media so I'm not sure it'll solve your issue.
