DISK Issues
Apple Community Support inquiry
Hi all,
I own a 2019 16-inch MacBook Pro with macOS Monterey version 12.6.
I also own a 4TB Western Digital WD My Passport HDD with USB-C port.
When I acquired the HDD, I made a partition to enable TimeMachine backups: 1TB for backups and 3TB left for other use.
Recently, the HDD was mostly likely unplugged during one of the backups operated by TimeMachine.
Since then, the 1TB Backup disk does not mount (except when my Mac turns off because it’s out of battery and I restart it later with the HDD already plugged into it) and I cannot see the files in my 3TB disk (no matter what).
Neither changing ports, nor changing cable, nor switching computers (even Windows PC) makes anything work.
For the 3TB My Passport, the data seems to be there, running First Aid fails and unmounting the disk also fails.
For the 1TB Backup, I expect the data should still be there as well, but again, First Aid fails and mounting the disk also fails (the opposite of the 3TB one for mounting/unmounting).
When using the WD app, only the 3TB My Passport disk is recognized by it.
When I run WD Utilities’ “Diagnose”, all tests succeed except for a “SMART status failed.” error.
When using Terminal, the few commands I am using give the following:
~ %ls /Volumes/My\ Passport/whatever/
ls: fts_read: Input/output error
~ %diskutil list

I do not want to go further trying out commands without understanding the risks of data loss, etc…
I would just like to retrieve the data from the 3TB My Passport disk.
I do not so much care about the 1TB Backup.
Does anyone know what is happening and how to fix it without sending the drive to an expensive data recovery service company?
Would erasing or deleting the 1TB volume, container, disk be sufficient to fix the whole HDD? If so, I would like to make sure this does not affect the 3TB part of it, and that it would allow me to access it again.
