Nick, rather than dedicating a drive to HD recordings, just add another
drive to the default storage group. Let Myth balance the i/o load
itself. If you have two HD recordings at the same time it should spool
one to each disk.

If you really want to have one disk just for HD you can create another
storage group and set all HD recordings to use it while the SD stuff
goes to the default storage group.
