Tracks ? Plural ? On BD-RE ?
>From the specs i read that BD-RE is overwriteable media
like DVD-RAM or DVD+RW. So the operating system does not
see any tracks but a random access disk.
It would therefore try to read the filesystem info
from the default address on such disks. In case of a
ISO 9660 filesystem this would be the blocks beginning
with number 16 (= 32 kB).
If your drive has address /dev/sr0 this command
dd bs=2048 skip=16 count=1 if=/dev/sr0 | od -c | less
will show the decisive line
0000000 001 C D 0 0 1 001 \0
If you overwrite the first 32 blocks by zeros then the media
will surely not be recognized as mountable ISO filesystem.
dd bs=2048 count=32 if=/dev/zero of=/dev/sr0
Have a nice day :)
