External DVD reader suddenly not working anymore I have a Iomega SuperSlim USB 2.0 8x DVD Writer External Optical Drive that I used without any issue on my Macbook Air.

Now all of a sudden it doesn't work anymore. The DVD spins, a "Audio CD" item pops up on the Finder sidebar and vanishes a few seconds after. Over and over again.

iTunes manages to get the track info after some attempts, so the DVD is readable.

I've tried to plug the same disc and DVD reader on a Windows machine, it worked seamlessly. So I guess this has something to do with the mac, maybe a recent software update?

Is there anything to do to troubleshoot such issues? It's the first time I have a hardware/driver issue (or similar) on my mac.

HW: MacBook Air 13-inch, early 2014 w/ 8GB or RAM and a Core i7
SW: OS X Yosemite 10.10.3
That it works fine on a Windows PC but not your Mac is puzzling.

Think back to when you know it worked properly. What software have you updated since then? That could be the cause. For example if you went from OSX 10.10.3 to 10.10.4 and that is the only change there may have been a problem with the update.

In that case you may want to try re-applying the latest Combo Updater for your current OS version. If it was an app of some sort you may have to contact the manufacturer to see if they have had similar issues from other customers.
