Changing the location of grafana.db

I am attempting to relocate the grafana.db file from the default location of /var/lib/grafana/grafana.db to a mounted drive. However, when I edit the the config file, setting data = /media/WDLabs/grafana, grafana will not start. I have copied the db file in there, BTW, and changed owner to grafana:grafana

Any ideas?

I worked out the error - a stupid one. Permissions!
