um.. I hope never mkudffs (you need to specify blocksize 2048 for optical media image) in mkudffs 2.x) can correct this..<br>

for Netbsd created 2.50 udf on hard drive file it requires<br>
-blocksize 512, but for real bluray image blocksize<br>
must be<br>
2048 (default)<br>
<br>
$ ./udf_test -blocksize 512 ~/udfimg.img > log<br>
<br>
there is linux (386) binary, but of course I compiled<br>
it anew,<br>
on termux. no scsi support, but othervise seems to work<br>
<br>
<br>
Tested my currently written discs:<br>
<br>
DVD-R:<br>
./udf_test /dev/sr0 | grep "block size"<br>
block size : 2048<br>
block size : 2048<br>
block size : 2048<br>
<br>
DVD+RW:<br>
./udf_test /dev/sr0 | grep "block size"<br>
block size : 2048<br>
block size : 2048<br>
block size : 2048<br>
<br>
<br>
cool, whole log quite verbose so I recommend to save it via<br>
'>' redirection to file.. (it prints summary at the end)<br>
<br>
<br>
Attach udf_test_log_DVD-R_growiso and udf_test_log_DVD+RW_dd<br>

udfinfo as mentioned in another thread, is not among udftools<br>
version 1.3 availabel on Leap 15.3. Tried to install<br>
udftools 2.3<br>
packaged for Tumbleweed, but it required a newer glibc. Will<br>
therefor update my Tumbleweed (dualboot) and install it there.<br>
<br>
<br>
ok, good luck with update!<br>

Regarding the warnings, I think I wrote I had root access when I created the images and burned the discs.<br>
I didn't use any extra mount/umount from terminal - the discs was also recognized by the Nautilus I think, ref. the manual<br>
