So I have an external WD Black drive thats 5TB. It's partitioned so that one partition is a normal APFS volume and the other is a 1TB partition for backups
A few days after I got the drive (back in February), I got this message
I thought it was a fluke and reformatted the drive and it worked fine. However, just earlier today, this message has come back up. There is nothing on the disk that is showing up, despite that there should be many backups
I tried running First Aid in Disk Utility and this is what I got
Running First Aid on “M1 Backups” (disk6s1)

I could erase it and try it, but what's the point of having a backup disk if all the data on it is going to magically disappear. This drive is brand new, maybe a month old.
I've never force ejected it before, I've always safely ejected it. However, the drive sometimes does make noise even after I've ejected it like stuff is still happening, but macOS showed no warnings or indications that it was still being used.
This is what Disk Utility > Info has to say about the partition
Any ideas?
