How To Transfer Data From HDD To Exising Truenas Pool? (25.10.3)

Absolute noob here. Pretty much the title. I managed to turn my old PC into a Truenas server and have created a pool from new WD Red Plus disks. I have an old WD Blue drive from my old PC with all my files on it and I want to get those files into the pool I've made.

I have seen people suggest importing or mounting the WD Blue drive, however, in Truenas OS version 25.10.3 I cannot find options to mount or import the drive anywhere in the Truenas interface. In the Storage tab I can select 'Import Pool', 'Disks', or 'Create Pool'. From my limited knowledge, Import Pool and Create Pool are not what I am looking for as the files on the drive are not in a pool yet, and creating one on that drive would wipe it. When I click on 'Disks' I can select my WD Blue HDD but the only options are 'Wipe' and 'Edit'. Edit presents me with no options to mount or import the disk.

Once I get past this step I have gathered I should use Rsync. How? Any help is greatly appreciated.

(Also, I was notified I should use 'flair' to denote the OS version of Truenas but I am also a huge reddit noob and do not know how to add flair. Hopefully posting the OS version in the title and body of the post is sufficient.)
