Split external Drive for TimeMachine and "other"

[Mcrumors David]

(Fact: Apple does not allow storing Time Machine Backup and any other files at the same time on a volume)

How do I create (from 1TB SD) two seperate drives and use TimeCapsule?

-- If only 1 volume = Time Machine Backup does backup
-- If 2 partitions = Time Machine Backup gives seemingly-unrelated error below

Try to create a new partition on Mac OS Extended instead of APFS (volume)

I may be misunderstanding what you are saying, but it's not a fact that apple doesn't allow you to store a time machine backup & any other files on the same drive. I do it all the time.

If you create both volumes in the same container, then they will share the free space available. But slowly with time, the timemachine backup will keep growing as long as there is free space available. And as already stated, there is nothing preventing to have other files on the same volume as timemachine.

As to the error reported in the first post, I don't think it has anything to do with the Time Machine setup. It seems that the OP has two Macintosh HDs that he's trying to back up to a single Time Machine. That is what doesn't work.

I don't use time machine, and never will use it.

However...
I would NOT use a drive that is intended for tm with anything else.
I would let that drive exist as "a time machine drive only".

Things will probably go better that way.

Does not work, same error

It's APFS. You don't want to "partition" it. You want to create a separate Volume within the APFS container. Select the "Container disk6" in Disk Utility then ask it to make a new APFS Volume. You can set the parameters on the Volume like encrypted, case-sensitive, etc. The new volume will be separate from the Time Machine volume. On your desktop you will see different external "drives" for each volume. The two volumes share the same free space in the container.

Yep. That's exactly what I have, they share the 1TB SD-card ...however the problem (nuisance) is:
TimeMachine only starts if I unmount the non-timemachine volume before

What's weird in the original post picture is that I see two "containers" listed under the SDXC device. One called disk5 and a separate container called disk6. That implies to me there are 2 GPT partitions on that device each with a separate APFS container. Am I seeing that correctly? That's very different than the external SSD I have on my Mac. I see one container disk which has two volumes underneath it. In my case, both APFS volumes get mounted at once and TM runs on the Time Machine volume no problem. Maybe the fact you seem to have GPT partitions is causing an issue.

Yeah dude that's an old screenshot ...here is my current config as mentioned 👉🏻

And this is what happens (unless I unmount all but my timemachine-volume) 👉🏻
