Installed new hard drive - now booting into emergency mode

view story

https://bbs.archlinux.org – I have been trying to install a new hard drive into my system, but when I have it plugged in, arch boots into emergency mode (it boots fine if I unplug it again). It goes through GRUB fine.Ithink the device names are being reassigned, as I ran an fdisk -l before and after. Without the new hard drive, fdisk shows device /dev/sda1 to be my 1TB hdd, and various partitions of /dev/sdb - archlinux is installed here; /dev/sdb3 is my /boot, /dev/sdb5 is my root and /dev/sdb6 is /home.However, when I plug in the new drive and run fdisk, /dev/sda1 is reassigned to /dev/sdb1, /dev/sdb moves to /dev/sdc (HowTos)
