Yes, if you are using our OS, you will have to setup the mounts manually. There is no automation to do that for you. For sda1, is that a partition on your 2TB ssd? Is sda2 another partition on that SSD or a different drive? I don't know how you created them, so it's hard to say why it won't mount.
There are no restrictions for mounting drives, so this should work.
Sudo mount /dev/sda1 /mnt/sda1 works
Sudo mount /dev/sda2 /mnt/sda2 gives error:
Mount: /mnt/sda2: wrong fs type , bad option, bad super block on /dev/sda2, missing codepage or helper program, or other error
