(1) I have a MyBook which, when mounted, generates a 'macOS can't repair the disk' message. I think this is from age and/or disconnecting improperly too often. The message goes on to say that it should be backed up and reformated as soon as possible, which I intend to do, but before doing so I'm wondering if it is possible and not inadvisable to open my iTunes library which is saved to it. I realize no changes to iTunes can be saved to the disk, but I want to view it if possible, unless this would further damage the disk, causing me to lose data on it. (2) [I'll repost this elsewhere on the forum if that's better] Another MyBook flashes the indicator light when connected, sounds to be powering up, and then goes offline. It's evidently not dead, but is there a way to be it to mount, if only to backup the data? Thanks in advance for any guidance.
