Need help from Old Toad

Hello Old Toad.


I wanted to ask you about a problem I'm having with one of our DVD burners. We are both using the same type of unit so maybe you can shed some light on the problem.

OWC Mercury Pro 24X DVDRW

I have all identical units from OWC. Same exact part number. All work perfectly, except for this one recent purchase. I am using the USB 3 interface on the Mac Mini.


A 2014 Mac Mini (OS 10.9.5) would never “see” the drive. (The DVD tray would open and close just fine, but that's it.) I would insert a blank disk into the drive and Disk Utilities would simply refuse to burn the disc because it thought I had no drive connected. I would unplug the drive and replace it with an identical unit and everything worked perfectly. I swapped the drives out about 3 times, always with the same results.


So here's the odd part. I returned the unit to OWC and they are unable to cause failure. I understand we could be dealing with a weird intermittent problem but I wanted to ask you if there are any “settings” in my Mac Mini that might cause this, or if you have any other ideas.

Did you try all available USB ports on the Mini?

Were you able to try that drive with another Mac?

Did you swap out cables also?


I use my drive with a Thunderbolt to FW adaptor since I don't have USB 3 and want the fastest read throughput possible.


With the unit attached to the Mini is it recognized in the Disk Burning section of the System Information window?
