Re: Is a disk rewritable?

Than you. That is exactly what I was looking for. The command displays either "Is not erasable" or "Is is erasable".

I don't know how they do it, but every disk-burning application I've
seen starts by determining the type of the disk (exactly the
information you're asking about).  I suspect some code-reading would
be the quickest way to an answer.



The type of disk, and a bunch of parameters, are encoded on the disk.
cdrecord -atip should print this information.
