After upgrade to 15.3.2, Mac cannot recognize Time Machine hard drive

I just updated my Mini M1 from 15.3.0 to 15.3.2. When it mounts my external 60TB RAID disk, I get the message "macOS can't repair the disk <name>".

I updated my MacStudio at the same time, and it CAN mount the RAID volume fine (read/write), and running Disk Utility there are no issues reported or fixed.

Next, I booted into the emergency mode (hold power button) and re-isntalled the OS, but it is back at 15.3.2.

At this point, I can only wait for Apple to fix this. Wiping the disk and re-installing the OS will bring back 15.3.2 - but what I really want is revert to 15.3 (15.3.0). No can do!

Thank you Apple, for removing system restore from TimeMachine.

The disk is formatted HFS (journaled). It looks like DiskUtility crashes because of the larger volume and and number of files when on my 32GB-RAM MacStudio the same disk has no issues - and Disk Utilty does not find any issues. Same OS version (15.3.2).

Using 4TB WD USB hard drive as Time Machine. After upgrading to 15.3.2 Sequoia on Thursday, my system says it cannot mount the hard drive. Mac does say it cannot mount the drive but does not explain the defect. Disk Utility Repair was of not help; it also could not mount the drive.

Using WD utilities, the disk checked out as OK. So, the WD utitilities can see the disk, but Sequoia 15.3.2 cannot.

Again, this is the external hard drive that I have used to back up my Mac Mini. Last successful backup was Wednesday.

A separate hard drive, a LaCie, used for storage, does not have this problem. Please advise

Seems a wd issue— not sure where this is "WD utitilities"

however I might suspect some firmware update is in order from WD—

if in doubt search the developers website or contact their: Support/Help/FAQ/Known issues/compatibility/updates…

report back if you find anything out

the update has disabled a G shuttle 42tb Raid drive with our latest work project on it.

Apple support unable to help.

Its a problem with privacy and security

they use to have 3 options

from 'Apple Store'

From 'Apple Store and known developers'

and

from 'anywhere'

anywhere has been removed as an option

I don't know about your G-shuttle, but trying to help with general advice (I'm using Areca RAID):

As a first step:

What I'm missing here is that any driver which is a system extension (like your G-shuttle) you must also set system security to allow kernel extensions (kExt are disallowed by default).

Enter macOS recovery (hold power button on M1):

https://docs.zepp.com/docs/1.0/guides/faq/apple-silicon/

and proceed to allow kernel extensions (point 2). Without that setting, the RAID driver will not load - and the disk is not visible.

Once you have allowed non-Apple kernel extensions, you need to allow your driver to run (Privacy and Security, the "anywhere" setting was removed years ago):

https://support-en.wd.com/app/answers/detailweb/a_id/31112

If the message "blocked extension" (like mentioned in the WD document) does not show; just open "Privacy and Security" yourself and check if there is a button (Allow) visible. Re-install the driver in case you are not sure if allowed already. Once you allow, the button disappears. After driver install, restart, then check "Privacy and Security" for any messages.

The update from 15 to 15.3.2 will not change the setting to allow kernel extensions; an update from a macOS older will require it because the setting did not exist. It may happen that a version-update requires re-allow a kext to load, and the message to "Allow" may not pop up after the update (see above how to fix).

Hope that helps,
