I have a 2010 iMac desktop and a 2012 MacBook Pro. I have had both from new. I have burnt and read CD's and DVDs on both. Both are running the latest version of El Capitan v10.11.6
Today I have a odd problem. I burnt some files to a DVD-R on the desktop. When it completed, it verified OK, but it did not appear on the desktop as an image. I ejected the DVD with the keyboard button and reinserted it. It appeared on the desktop as "Untitled DVD". When opened, it appeared to be blank, with the words "Recordable DVD" in the window. No files were listed.
I took this DVD to the MacBook Pro and inserted it. It opened and all the files were listed correctly and the contents were there. So the iMac is writing DVD-R discs, but not reading them.
I needed to make two DVDs, so I did the second one on the MacBook Pro. When that had finished burning, the icon appeared on the desktop and could open it and read all the files. I took this DVD back to the iMac and it also appeared as "untitled DVD" and no contents showed when opened, just the "Recordable DVD" in the list.
I tried to read some more DVD-R that I had burnt on the desktop in the last couple of years with the same result. They had previously worked on this iMac and they were burnt on it. I check all the discs that I burn before storing them. They all work fine on the MacBook Pro.
Finally I checked some other DVDs that I had burnt on the iMac. These were CD-R, DVD+R and DVD+RW DL. As well as checking some burnt discs that I had been sent. They all appear on the desktop and open and work. So do some original manufactured DVDs which are not burnt copies.
Why won't the iMac read DVD-R discs that it or the MacBook Pro have burnt, yet read all other formats. Even though the older DVD-R that were burnt on it used to work on it?
I don't have any unused DVDs in formats other than DVD-R at the moment to see if it is just that format that's going wrong.
