Satellite Pro A200 running Vista Home Premium. The CD/DVD drive does not recognise a lot of old discs written from an XP installation or old XP installation discs. There is no error message, nothing at all, right clicking the drive & looking at properties shows an empty disc. I have just downloaded an ISO file (GParted CD live). I burnt it to a CD & everything worked fine but when I tried to run it - nothing. Is this a Vista issue or is the drive faulty?
