DVD-RW media detected as CD?

Hi all,

I have been using DVD-RWs on my Toshiba SD-R5002 drive.

All of a sudden yesterday all my DVD-RW media is being detected as CD media.

I have tried using the newest versions of InstantCD, Nero, and Alcohol 120% (ignore TOC) to erase these with full & quick erose. But the erase cycle ends in around two minutes always OR comes up with a “sense” error.

This is happening with all my DVD-RW media that used to work fine until yesterday.

Can anyone tell me what’s wrong?

Thanks
