Re: Blanking/Formating a BD-RE
If someone can provide me some tool or instructions how to do it I could
try it on another PC with BD-RE drive.
If the only goal is to render media unmountable, then, as Thomas
suggested, you should find a way to nullify beginning of media. One way
is to 'dd if=/dev/zero bs=1k count=64 | growisofs -Z
/dev/cdrom=/dev/fd/0'. If you ought to nullify the whole thing, e.g. for
privacy reasons, then 'growisofs -Z /dev/cdrom=/dev/zero' would do.
However!!! As it's time consuming procedure it's probably more
appropriate to spend this time on 'dvd+rw-format -format=full
/dev/cdrom', because it will also verify media for eventual defects. On
the other hand if current data-set is much less than media capacity and
you want to nullify only this data, you can save time by figuring out
how large is the data-set and adjusting count in above mentioned dd
command accordingly. For example take "1k-blocks" value from 'df -k
/mnt/cdrom' output and feed it as count to dd. A.
