Optiarc AD-5560A: Can't Read CDs, only DVDs

[qanda]This thread is about the Optiarc AD-5540A. Click here to see full specs[/qanda]My Optiarc AD-5560A DVD rw drive cannot read CDs at all. (but can read DVDs without any problems) When I load a valid CD-R into the drive, it asks if I wish to format it.

My system -
machine: Dell Latitude D630
OS: Vista SP1
CD burn software: Roxio Easy Media Creator 9
Optiarc Driver: Microsoft, 2006, 6.0.6001.18000 (under Device Mgr)
Optiarc Firmware: DD12, A02 (latest off the Dell support site)

Two oddities,
1-The Dell Support site doesn’t have a Vista driver for this drive,
2-I read DVDs, write CDs & DVDs with no problem. I just can read a CD

Windows Update says the driver is the latest version. Am I missing something? (Thanks in-advance)

NO drivers are needed anyway.

Boot from a CD to see if the drive CD part is dead or not.
