How do I mount/find a second HDD in Ubuntu?

Hello there and first off apologies if anything I describe is hard to understand, I'll try to be as clear as possible but I'm still a beginner at using Ubuntu. So off to the question:

I'm using Ubuntu with WLS. It's worked fine for the most part but here's my problem:

I've been doing the Odin Project and reached the boilerplate part. Coding and all that. However I installed Ubuntu on my C: drive while placing my programming projects on D: (C is where I keep all the important stuff such as OS and is just a 120GB SSD while D: is a 1TB HDD)

Now at first I tried using lsblk and it only gave me this:

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 256G 0 disk sdb 8:16 0 256G 0 disk /

Which is a bit weird since my SSD is 120. I tried first to just go to the disk D directory but it couldn't find it. So I googled how to add a HDD to Ubuntu and doing sudo lshw -C disk, it asks me for my Sudo PW. I use it, I don't get any errors but I also get nothing showing up. If I run the command again, it just repeats with no error.

I looked it up here and I can use this How to mount/access my second hard drive? however it still only detects a 256GB virtual hdd?

TL:DR I want to be able to access my html coding file via the ubuntu terminal while they are in separate HDDs. Apologies in advance if it sounds confusing and thanks for any help.

Edit:After seeing everyone's answers, I've decided I'll just scrap WSL and use a VM with the OS in it. Seems simpler that way. Thanks for the help anyway.
