okay so I finished setting up the 1 TB HDD. Just copied everything from the pen drive to this, seems to be working. Realized Samba was not working because apparently you now have to use systemd instead of init. So finished setting that up. However, now I have another problem, SSH is very slow. If I try to SSH, I get the username prompt, then after 5 minutes I get the password prompt, If I try to do pacman -Syu after that, it times out and gives an error. Transmission seems to be working fine. Any clues? A bit of googling suggested that disabling ipv6 might solve this, but the instructions were for a different distro.
It seemed to be working fine on this HDD before I moved to systemd
