External Disk Drive Problem

I got this error on Big Sur, 11.5.2 when I tried to mount an Audible/Brilliance book on MP3 cd into the Music App (iTunes) using an LG external USB optical disk drive. I had also tried opening the disk on my Sony BluRay player, the only other disk machine I own, to no avail.

The Disk showed up in Disk Utility, but was greyed out and when trying to mount it I got the com.apple.DiskManagement.disenter error 49153 Error.

After much searching and effort I found the post by M. Bedit back in March. I was able to extract the mp3 files doing the following;

1) From Disk Utility, I selected the external disk drive and created a .dmg image copy on my 2014 MacBook Air HD.

2) Using a 3rd party app, "The Unarchiver" I was able to extract the files.

3) Drag and Dropped these into Music, and then was able to listen to the book.
