Comment 3 for bug 1264804

Hi,

the drive tells libburn that the medium is not a DVD-RW
but a DVD+R. xorriso forwards this info:

> Media current: DVD+R
> Media status : is written , is closed

The perception of media type stems from "00 1b" in the reply
to the GET CONFIGURATION command

> GET CONFIGURATION
> 46 00 00 00 00 00 00 01 64 00
> From drive: 356b
> 00 00 01 60 00 00 00 1b [...]

The xorriso command -blank as_needed applies only to
erasable media and to overwritable media.
DVD+R is not among them.
Thus you get:

> xorriso : FAILURE : Media is not of erasable type

> HP DVD+R RW

Well, there are DVD+RW, DVD-RW, and DVD+R.

If you see printed on the disc a large "RW" in a square label,
and underneath smaller "DVD+R", then it is indeed a DVD+R
and not erasable.
The misleading "RW" is the label of the "DVD+RW Alliance"
which invented both DVD+R and DVD+RW media.

Have a nice day :)
