Operation failed…
I see this thread Help with 69845 disk utility error?

so I tried it to but I have an error
diskutil umount /dev/disk3
disk3 was already unmounted or it has a partitioning scheme so use "diskutil unmountDisk" instead
martit26@MacBookPro ~ % fsck_apfs /dev/disk3
error: device /dev/rdisk3 failed to open with error: Operation not permitted
what can I do?

Thanks,

What model Mac and version of macOS are you using? How old is this drive? Hard drive (HDD) or SSD? What is the exact WD model number?
 
MacOS 15.4 (24E248)
WD's my passport 2021 WD 2TB My Passport for Mac, Navy, Portable External Hard Drive with backup

I have a password normally to open it. but I don't know if fsck_apfs need to be able to have the password.

Are you using macOS File Vault or using the WD 3rd party encryption and password protection? If using WD, make sure you have the latest version of WD software and drive firmware updates installed.
 
I am using using the WD 3rd party encryption and password protection.
in case, I put the lastest version of WD from WD software download

WD Discovery and​

WD Drive Utilities​


which one is for drive firmware?

"error: Try running fsck against the entire APFS container instead of a volume"

Usually worth trying, it even says it in your little initial error output. In Disk Utility, change the view settings to show all devices, and then just run first aid (which will run fsck anyways) on the actual drive itself which will be the top most item beyond just whatever the volume name is and the container, though you can run it on the container as well afterwards if you want.

Because these mechanical external hard drives tend to suck, and aren't exactly super reliable, if this is a portable drive that you've carried around with you a lot, or it's older than like five years or so, I would not be shocked at all if it's starting to show signs of early failure.
 
what is the command to run fsck against the entire APFS container?

I did not move this portable drive except when my IT guy asked me to bring it on Friday morning and this happens. I did not see any early sign of early failure unfortunately, to avoid this issue!
what type of portable drive do you advice to buy?

thanks,

OP:

I don't have "the answer" to your problem.

But it if was MY drive, I'd try this:

First, I'd erase the entire drive.
Yes -- erase it, wipe it out.

Then, I'd just run time machine "over it" again -- creating a BRAND NEW backup.
I'm going to take a completely wild guess that MOST of what you want on the drive is representative of "what's on" your Mac at this moment (I could be wrong).

So... a fresh backup should take care of that.

Finally, I WOULD NOT use encryption on a backup drive, unless there is some absolute, positive reason why you MUST do so (such as orders from an employer, etc.).***

A backup is supposed to be EASY to "get to" when you need it.
Because most folks reach for their backup "in a moment of need".
If you need "security", lock the drive up at night or hide it.

As you have discovered, it may be "the encryption" that is PREVENTING YOU from gaining access to the drive.

Hmmm... one other thing.
WD drives often come with some Western Digital "proprietary" software on them.
The FIRST THING a Mac user should do is to REMOVE this software, and reformat the drive using Disk Utility.
One can download the WD drive management app from their support site to do this.

Good luck.

*** I concede that there ARE reasons to encrypt a backup now and then.
Personal example:
I have a backup drive I keep in my car (as "offsite storage"). On one partition of that drive (not the entire drive), I have encryption because bank records, etc., are on it. Someone could steal the car, but all they'll get "is the drive", not the bank info.

But on my other backups inside the house, ALL are "in the clear" (NOT encrypted)...
