[Bug 1264804] Re: Cannot blank DVD-RW

2013-12-29 Thread Thomas Schmitt
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 :)

Thomas
