Are any of the autosave backup session file openable?

What happens when you try import session (or track by track)... I exepct it will not work, but try?

Sounds like you might be making two backups one with CCC and one some other way? Are both bad? If so it says the session as likely corrupt when backed up. The usual recommendation here is three, ideally done in different ways/to different locations (e.g. one on cloud storage).

I hope when you say you tried to open an old session that sounds like it might have been an archive sitting on the third external disk drive you mention that you did not just try to open it in place... if so you are then running with zero backups and if Pro Tools ate that single archive you may be screwed. Always copy stuff out of a backup before testing, for any software/app. I'd copy the whole session folder into a scratch folder on the internal boot SSD (HFS+ or APFS whatever that OS uses) and test stuff there. I assume you have an internal SSD, I can't guess what model Mac Mini you have.


I can't follow what you really did you clone drives with CCC but has that anything to do with this problem--is that clone what you are trying to recover the session from? If so how exactly did you get there session off the backup/clone to try? Or was this session on the other drive and how do you get sessions there? Are all volumes everything except your new macOS boot volume is HFS+? (check don't guess, I suspect they are fine, but clutching at straws). And no other problems? No strange errors/warnings about disks or file systems in system.log in the Console.app?
