THIS SITE is great. Thank you for the replies you so promptly sent. No luck yet. My drive will play Cd's AND DVD's all day long and when I put a rewritable in another computer...VIOLA. NOW. I put a NEW drive in my Toshiba and IT won't write!! Everything BUT write. For now I am writing to a 4g stick and transferring to CD on another computer. It is music wit audiostrobe and the files are large.
