I have a Lenovo ideapad S340 with Zorin OS 16.1(if that makes a difference). It has a 120gb SSD and a 1TB HDD. I run everything from the SSD but the HDD is recognised as an external hardrive. After an update, I can't even do anything to the files in the HDD. I can't change or make new files, and to access, I have to copy everything over. I looked elsewhere and someone told me to change permissions for user but that didn't work either.
Question: How do I access all my files normally(i.e. read + edit) and make Zorin detect it as an internal drive. I am okay with complicated steps as I am adequately adept. Would prefer to copypasta commands if required.
