Contents of DVDs don't appear and I cannot burn DVDs.

 

About two months ago I became unable to burn a DVD.

One month ago I became unable to see the contents of DVDs, though my iMac can recognize and read an audio CD..

 

I've tried accessing information from commercial as well as Sony DVD-R 16X discs made by a friend using his iMac—to see if my friend's discs were blank, we opened them in his iMac and found all the programs; I tried again on my iMac and still can't see any content.

 

I have repaired permissions using Disc Utility, but the problems were not solved.

 

Discs appear on the desktop as "Untitled DVD".  When I open "Disc Utility", the discs themselves do not show up, and the image for "SuperDrive" seems greyed out; still, when I select "SuperDrive" I can get "Info" and instructions for erasing a disk.

 

I was advised to open System Preferences>Users & Groups, unlock the lock, click on the little plus icon, make a new administrative account, then log out & into the new account; but the problems were not solved.


iMac, OS X Mountain Lion (10.8.2), 2.66 GHz Intel Core i5, 4 GB 1067 M

    The drives do malfunction; I've had several that had to be replaced. Does yours show up here: Apple > about this Mac > more info > System Report > Disc Burning?

     

    If it doesn't recognize any disks, I'd suggest making an appointment at your nearest Genius Bar - diagnosis is free (if you've covered by warranty, do call Apple - take advantage of your warranty).

    Hi Babowa,

    It doesn't seem to recognize any disks - there is one more troubleshooting step to do (may or may not have results, but won't hurt):

     

    Reset SMC and PRAM:

    Other than that, I'd say a Genius Bar appointment is the next step....
