Ok... is clear that I am not English mother tongue and I do not know the English language.
Thanks for the correction ... sooner or later I will learn a little bit.
Ok... but in this way my SAMSUNG standalone will not read the BD-RE!
In this case, I'm again to the initial problem.
My BD-RE DL has these values:
23,652,352 sectors
48,440,016,896 bytes
Do you think it's been formatted with "spare area"?
