Edit: My deck came in, and I gave up on trying to do this. Thanks to everyone who replied and tried to help.
———————

I have the OS installed on a machine with a Ryzen 3200g, 32gb of ram, and a 256gb SSD. The install went just fine, and SteamOS updated to 3.2. I bought a 1tb Sandisk microSD card and wanted to prepare it for my Steam Deck (when I'm finally able to order it). So, I throw my microSD into a USB adapter, plug it into my PC (running SteamOS 3.2), the OS notices the card, the format option becomes available, I tell it to format, annnnd....I get "Format Error. No microSD card found. Please insert a microSD card into the card slot and try again." So...is there a trick to this? How do I tell the OS that my microSD is, in fact, the droid it is looking for?

Desktop mode will read the card, but I don't see any options anywhere to format it. And even IF I could format it, would game mode still fail to see the card because it isn't in the "card slot"? I tried all of my USB ports...SteamOS doesn't consider any of them to be my "card slot". How can I get this card formatted and recognized properly in SteamOS so I can set it up with games and emulators? Thanks for your time should you choose to reply.

Could you please run "lsblk -f" in the terminal and post the output here?

One of the potential problems here is that the SD Card is formated in exfat rather than fat32, you should try formatting it using Rufus to fat32 as a non bootable drive.

If he want to format it for the Deck, which is Linux, you should try ext4 honestly.

Command should be "sudo mkfs.ext4 /dev/sda1"

Just keep in mind, karmarainsblue, that the ext4 filesystem can't be natively read on Windows. You'll have to find a workaround if you want to transfer files using that card as well (At least from a windows computer).

The deck's formatting tool is hardcoded for use with "/dev/mmcblk0p1" node. That's why you're greeted with error as soon as you try to format any other device since it can't find the node
