Do DVDs in the bluray drive play OK?
I'd consider reinstalling the drivers, and checking that both SATA and power cables are plugged in properly.
EDIT: Also, do you have AnyDVD, or AnyDVD HD? The normal version won't play BDs or HD-DVDs.
nope, dvds don't play in the drive as it is not recognized at all by Windows except in the Disk Management section of Computer Management. I'm going to try to uninstall it from the computer it is in and move it to my main computer and see what happens. Thanks very much for your help. Oh yes, forgot, it used to work but I had not used it for months until yesterday.
