More info:

My array is made up of /dev/sda, sdb, sdc, and sdd.  However they are
not mounted right now.  My OS is booted off of /dev/sde.  I am running
ubuntu 9.04

mdadm -Q --detail /dev/md0
mdadm: md device /dev/md0 does not appear to be active.

Where do I take if from here?  I'm not up on this as much as I should be
at all.  In fact I am quite a newbe to this... Any help would be greatly
appreciated.

Thanks
Rick
