OwnCloud 10.0.4 (stable) guidance for mounting a USB drive

I have OwnCloud running on my Raspberry Pi 3 running on top of DietPi. I have a 3 terabyte external hard drive (powered) and formatted to NTFS connected to my Pi, I have discovered that even though the drive is spinning OwnCloud is not using it. I believe I have to mount it by giving it commands but I have no idea where to find instructions about how to do this (believe me I have tried to find a solution, For... Three... Days!) I would appreciate if I could get some steps explained to me as even though I do work in IT coding is not my thing.

Thank you.

Please paste the output of



mount -l


cat /etc/fstab

Maybe this helps someone to help you...
