Q: I purchased an external CD drive because the internal one died.  When I try using the new drive I get the following msg "The attempt to burn a disc failed.  The device is not accessable, probably because it was removed"

I purchased an external CD drive for my MacBook,the internaldrive had died.  When I tried using the new drive I got the following msg "The attempt to burn a disc failed.  The device is not accessable, probably because it was removed"  I contacted OWC and tried to work the issue with them, we gave up and OWC sent me a replacement.  I connected the replacement and am getting the same message.  Any thoughts?
