Brand new 1TB Samsung SSD T7 Shield can't format

[OldCorpse]

About a week ago I bought a brand new Samsung 1TB SSD T7 Shield on Amazon.

Today, I tried to format it, using Disk Utility, (select volume - Erase), on my new 15" M2 MBA, but the dropdown menu only shows options:

1) Mac OS Extended (Journaled)
2) Mac OS Extended (Case-sensitive, Journaled)
and
3) ExFat
4) MS-DOS (FAT)

So I went ahead and formatted it in Mac OS Extended (Journaled), Ejected it, disconnected from my MBA, reconnected it, and tried to format again, but the same options appear.

IMPORTANT: Earlier in the day, I formatted two Crucial SSDs 1TB and 2TB that I bought together with the Samsung. I had no problem (except weirdly at first I couldn't rename the drives from the Disk Utility dialogue in Erase, I had to rename it by rightclicking the volume on my desktop and selecting Rename from the dropdown menu). All the options showed up. I successfully formatted both volumes to APFS.

I used the same cable on the Samsung T7 Shield and the same port on my MBA to connect the Samsung to my MBA as when I successfully formatted both the Crucials.

I then changed to the cable supplied with the Samsung and connected to the other port on my MBA. Same result - the only options were the ones indicated.

I renamed the Samsung volume yet again (this time in Disk Utility) and erased/formatted again to Mac OS Extended Journaled - because the same options appeared with no APFS.

The "Get Info" from the right-click drop down menu on my desktop shows the Samsung Sharing & Permissions as me with Read & Write privileges.

The Samsung came formatted in ExFat.

Disk Utility shows 663.7MB used and 999.54GB available.

The "Partition" tab on the Disk Utility is grayed out when the Samsung volume is selected.

I ran First Aid on the volume and it checks out fine.

My just bought 15" M2 MBA 16/1 is running the latest Sonoma 14.1.2.

Any idea what's going on? Why don't other formatting options - APFS flavors - show up in Disk Utility, but there is no such problem with the Crucial drives? What am I missing?

Thank you for any insight!

Select menu Disk Utility > View > Show All Devices .. then select the top most device representing your T7 and then Erase.

Thank you, Bigwaff, that was it! I knew I must be missing something obvious. I never selected "View", because somehow I assumed that by default it showed everything - my bad. I still wonder why I didn't have this issue with the Crucial drives...

Also, in case anyone else has the same issue and reads this in the future, you obviously also have to select "GUID" otherwise, if it's sitting at something like "Master Boot Record" as it was in the case of my T7, it'll still show only the same non-APFS options I was puzzled by.

Thank you again Bigwaff, I'm really grateful that there are generously helpful people on these boards. Soon, I'll be embarking on a pretty complicated mac mini home server network adventure and I can only imagine how these boards are going to be a desperately needed safety net (mac mini as server for music streaming, TM backups etc.).
