Home assistant with HDD dedicated for Motion Eye

Hi everyone,

I have a home assistant installation on an INtel miniPC with J1900 processor.
Home Assistant is installed on a mSata module and everything works correctly.
This PC has the possibility to add a SATA disk, what I would like to do is to be able to make home assistant see this second 1Tb disk in order to save the movies/snapshots captured by MotionEye.
How can I do this? I’ve been searching for some time but can’t find a solution.

Thank you all in advance.
