My notebook has an internal Matsushita BD-CMB UJ-20 ATA (Blu-ray DVD) on a Vista system that came with pre-installed Power2Go software to deal with the drive.
Last week, I got an external Pioneer.DVR-X162Q drive.
So, I decided to test creating the following media on each drive: CD-R, CD-RW, DVD-R, DVD+R, and DVD RW.
For each media I attempted to create a "Mastered" version and a "Live" version.
ALL worked in the Pioneer.
All, except the CD-RW, worked on the Matsushita.
When I right-clicked to format the CD-RW in the Matsushita, I was informed that there was no media.
But, ISO Buster detected the blank CD-RW on the Matsushita.
So, I guess that there is either a problem in the Power2Go software for formatting CD-RW, or there is a firmware issue that ISO Buster knows how to bypass,
The Matsushita does recognize CD-RW that were recorded by the Pioneer.
I've suspected this problem for quite a while, but was not able to follow up until now.
Fortunatelly, warranty is 2 years (purchased on 31 May 2008).
