I did the same recently. My mythtv recording are stored in a directory called /video this was mounted on hda. I moved the video dir to /video2 and mounted hdb as /video then copied accross the contents, therby increasing the space from 60G to 120G and also freeing up loads of space on the main drive. -- Regards, ~CM
