I just got a new Optiarc DVDRW drive today, an AD-7191S. It replaced an NEC ND-3550A, I wanted a SATA drive and something with LightScribe functionality. Since both the new and old drives were from the same "gene pool" I figured it would be alright.
Unfortunately, it didn't take me long to find a problem.
After using the drive for a few read tests and a LightScribe burn, the drive appered to stop reading media, ignoring inserted media and responding with a "Please insert a disc" message every time I tried to access it.
After a lot of trial and error, I found a common thread. It seems that my new Opty doesn't like media with darkly coloured substrates, and between Memorex Black, MPO Hi-Space, Prodisc coloured discs, I have a rather massive stash of dark substrate CDs.
All this stuff worked fine on the ND-3550A and still works great on my Samsung DVD+-RW drive, and due to the latter fact I am not that worried.
All the same I'd like to sort this nonsense out.
Should I return the drive to the seller, or is this kind of behaviour something I should have expected? Can I fix this, or would Optiarc take me seriously if I contacted them to complain?
