I recently cleared about 500GB of junk from my HDD. Since I'm pretty low on space on my Arch install, I figured I'd dedicate 200GB of that to /home. Problem is that my /home partition is located on my SSD, not the HDD. I'm not sure how I'm supposed to migrate /home to another drive.
Recovery, EFI, Windows Boot, Arch Root Partition, Arch /home Partition and 20GB overhead for the SSD. The HDD is just a big dumping ground.
What I want is to move the /home partition safely over to the HDD (new 200GB partition), then merge the old /home with the root partition to create a bigger root partition.
