Samsung T7 Shield SSD External Drive Will Not Mount On New OS

I have two Macbook Air's with one running Ventura 13.6, another has Monterey 12.2.1 and My M1 Mac Mini is running Sonoma 14.3.1 and my Samsung T7 Shield will NOT mount on any of them.

BUT when I connect the Samsung T7 Shied to my old iMac running Monterey 12.6.3 OS my Samsung T7 Shield mounts!

This is an apple issue on the new versions of their OS.

This is NOT a cable issue.

This can be resolved by running repair in the diagnostics.

How can this be fixed. I know Apple is going to tell me it's a Samsung issue. But it's not a coincidence that the new Mac OS doesn't recognize the SSD.

Has anyone found a solution for this?

Thanks

Mac mini, macOS 14.3

Do you have Samsung software installed for that drive? Usually there is no need for that, and that Samsung sw might now be incompatible with newest macOS.

Usually it is best to use macOS Disk Utility format the device (not just the volumes under it) as APFS (GUID). 3rd party disk utilities are usually not needed.

I found the solution. When I upgraded the OS to Sonoma 14.4 on my Mac M1 mini and MacBook Airs the Samsung T7 Shield mounted and appears on my desktop. It appears you need to upgrade to Somoma 14.4 for the external Samsung HD to operate properly.
