Can I use the 1 TB drive from the Series 3 HDXL?

I replaced the 1 TB hard drive in my Series 3 HDXL with a 2 TB several years back to increase the storage. That 1 TB drive has been sitting around since then. Can I use it as external storage on my Roamio Pro (6 tuner) and how would I go about doing that? it is a WD Green (WD10evvs) 1 tb DRIVE.
Thanks,
