When attempting to burn a DVD tonight I was getting a message from within the OSX Disk Utility stating that the Disc Drive was busy. At first I thought it must be a DVD that was not compatible with the DVD burner however I attempted to use three different types of DVD’s with the same message. Finally I realized that I had VMWare Fusion running and one of the VM’s I was using at the time was sharing the Disc Drive with the host OS or OSX. Below are more details about what the message from the OSX Disk Utility will look like and how to remove the disc drive from being shared with a VMWare image.
The disc drive is busy. Please choose another drive.
As you can see above the message states that the disc drive is busy and to use another drive. I obviously knew this was not the case since I had just inserted a DVD into the drive. If you are running any active VM’s using something like VMWare Fusion then the issue is likely that the disc drive is being shared with one of the VM’s and you simply need to disconnect it from the VM as shown in the below example image.
Disconnect OSX Disc Drive From Being Shared With VMWare Fusion Image:
To disconnect the drive open any active VMWare windows, click the disc drive icon, and select Disconnect CD/DVD. In the above example the drive has already been disconnected but as you can see this is also where you would reconnect the drive if you need it as a resource after you are done burning a CD or DVD. With the disc drive disconnected you can now proceed with burning the image you first set out to burn.
Burn Image To DVD On OSX:
The moral of the story is don’t connect shared resources to VM images until you need them or you could run into resource issues or other issues such as the one noted above.
