Disk Utility automatically creates two partitions in USB drive without warning

So, I was able to format the drive for it to have only one, whole, partition, by selecting "Master Boot Record".

1) Before the formatting (notice the "Master Boot Record" text under the name of the disk and "Child count: 1"):

2) Choosing the parameters:

3) Process completed (the "2" in the "Child count" line is already visible):

4) The result:

I don't understand: did you come to the thread of a person who probably has their reasons to ask 'Hey guys: this is creating two partitions. Why? Can I change this behavior?' to tell them 'I know for a fact that this is inconsequential in your life, so stop bothering about it'? I mean: who are you? Do you know me? Haha.

This has to do with me inserting that pen drive in my Samsung smart TV to relax while watching the photos of a vacation and stuff, and having to spend 1 minute trying to understand if the correct partition is "Ultra (1)" or "Ultra (2)".

Happy? Do you approve my thread now?

Interesting contribution, and one certainly worth exploring, out of curiosity, in the future. But I still don't want stuff done to my drives without my expressed request, so using MBR is the correct workaround for my issue.

I've never said this was Apple's "fault". Merely that I've noticed this behavior starting with Big Sur...which doesn't exclude that I could have been distracted up to now and simply hadn't noticed this before, or even that this indeed has started to happen now, but could easily be something that all OS have just begun to do.

In either case, absolutely no personal attack against Apple, which hardwares and softwares I've been using for two decades and I adore.

"You do realize that..." No, I don't. That's why I'm here, asking for clarifications.

"...via the View Popup menu ("Show all devices")." "Show all devices" doesn't show any additional partition for drives that were formatted using MBR. The description also reads "Child count: 1" when I format the drive using MBR.

If there's indeed a partition there, and it's SO hidden, at this point, I honestly don't care.

The reason why I do care with GPM is because, when inserting the GPM-formatted drive into one of the USB ports of my TV, it opens up two folders and I have to magically "come up", myself, which one is the one I've uploaded stuff onto, especially because the folders are named identically, with only an arbitrary "1" and "2" to distinguish them.

The drive and the TV don't behave like this when I format the drive with MBR, so it's OK by me.

Exactly, that's what I'm talking about. I thought it was me making things up, but Apple actually recommends GUID Partition Map, which, in my case, is the culprit: it parts the drive in two.

Which part, exactly? It's a technical article about one and the other's advantages and disadvantages...one is more modern, the other more compatible... So?
