Disk Utility RAID Uh Oh...

Mac Pro wouldn't boot this morning; looks like the 2-drive Disk Utility (v11.1) mirrored RAID pair is degraded.

Running 10.5.8 (until today) on two identical Seagate ST3750330AS 750 Gb SATA drives.

Trying to get the intact RAID member to serve as a Restore source, I repartitioned the degraded member drive.

Now the drive I wanted to Restore from won't mount, nor is it visible in DU.

Is there some Terminal magic I can use to get it to a mountable condition?

Is there any recourse to get the intact but now solo RAID volume working so I can "clone" that volume to another disk?

Or (please say no!) is my data "gone?"
