Q: Unable to Erase/Eject DVD in Disk Utility

I am trying to erase a DVD RAM disc using Disk Utility.  Since installing El Capitan I keep finding that the 'Erase' button is greyed out.  I changed to a DVD-RW and find that I can't erase that either.

 

This happens with both my internal DVD Reader/writer and my external Blu-Ray/DVD Reader/Writer.

 

Furthermore the 'Eject' button next to the disk doesn't work properly.  It removes the Disk's icon from the desktop but it won't eject the disc itself.  Sometimes I can use Cmd+E to eject the disk from the desktop. At other times the only way to eject is to restart my iMac whilst holding down the right mouse key.

 

Is this a fault with the OS X installation?
