Exchange 2K- how to move Public Store

Setup: W2K with SP3 + Exchange 2K Enterprise with SP2. Multiple hard drives. 1 drive per Storage Group. Have 4 storage groups. Not able to backup First Storage Group. Possible HW drive problems. Can access all mailboxes and folders, no problems.

Need to move all Private and Public stores to Second Storage Group on another HD. I can easily move individual Milboxes, however, I can not find any info on how to move Public Store or Individual public folders to another Storage Group on the same server
