How to partition external hard drive? Partition option greyed out

I'm trying to partition my Seagate 2TB external hard drive with my MacBook Air M1.

I've formatted it to Mac OS Extended (Journaled) and ExFAT but neither solves the issue.

I've attached two screenshots which show I also don't get the option to add a 'Scheme' e.g. GUID partition map.

MacBook Air 13″, macOS 11.1

Partition New Seagate 2TB drive The new drive shows using Disk Utility. However the "Partition" option at the top of the window is greyed-out. I have done "First Aid". I suspect that the solution is by way of "Erase", but here I find myself nervous as to which of the options to go with. When I choose "Seagate Portable Media", I have the option to assign a name, chose a Format, (and assume I should go with " Mac OS Extended Journaled) and a "Scheme" (where the options are "GUID Partition Map", Master Boot Record" and Apple Partition Map". I don't know which is what is needed for me to start partitioning the drive. When I choose "Untitled" (which is a sub-level below the Seagate Portable Media item on the far left), I get four options, with "Mac OS Extended (Journaled) - which I figure is the best option - and then "Mac OS Extended (Case-sensitive) Journaled, MS-DOS (FAT) and ExFAT.

Unable to partition external hard drive on Mac using Mojave I have erased and reformatted several times, but partition in Disk Utilities continues to be greyed out. I have even tried different Macs with Mojave. I have other external drives partitioned, and First Aid doesn't show anything wrong with the external drive. I am really at a loss.

For a newer Mac, use APFS. Doing so well me and you do not need to partition the desk, you can create multiple volumes within the container and resize them as needed on the fly (including decreasing their size, which you can easily do with a partition).
