I have an external HDD (4TB G-Drive) 2 or 3 years old. I use it mainly for TM backups, and also for archiving some stuff. DriveDx rates it as "Average 52.1%". It seems to function just fine. But I've become aware recently that there's a user ID mismatch between my current system (and more recent backups) and my previous system (and earlier backups). 501 now; 502 previously. No idea whether that's relevant to this question??
Anyway to the immediate point: I can't recall if I've ever tried running First Aid on this drive. But on several attempts recently it's been a failure. It gets stuck on "checking catalogue file" for quite a while (half hour maybe?). Then it goes to "checking multi-linked files" and that's where it really hangs. I could leave it overnight and it's still at that point in the morning. So then I force quit and give up. I've tried it through CleanMyMac X, and in Disk Utility itself both from my boot system and from Recovery. Same result every time.
From a bit of research I get the impression this shouldn't be how it is. Can anyone advise please. Thanks.
