DVD External Drive not recognized
I have a Samsung USB2.0 DVD/CD writer for Karaoke that powers through the USB connector. While it worked on my older iMac, my new one will not recognize the external drive. I have it connected using an adapter to the Thunderbolt port. The blue light is blinking, but it will not open the slot for a CD/DVD. I have tried researching the issue without any luck. The finder setting are correct and I have restarted without any success.
