There would only be 4 things I might consider:
The drive needs to be reseated.
Look for the fix for the upper filters or lower filters in the registry. This might effect other types of burning software, don't know.
Since it is a new drive, I would doubt this is the problem, but check if there is a firmware update for the drive. The one I had would not show up in Computer unless I opened the tray. Then it would show up for a few seconds to a few minutes.
Hopefully this isn't it but possibly a laser has failed on the drive, or basically the drive needs to be replaced.
