New user, disk encryption(second drive) question

I’ve done everything up to this point:

It appears to have worked perfectly, aside from I’m only able to create/edit files under the root account(but I was root when mounting the device, which I guess answers that query).

For a mount point - I’m easy. I guess /mnt/data, /media/data, or just /data would make sense to me. It’ll mainly be for storing things outside of the traditional home directory.

Thanks again!
