Back up all data on the drive, then try repairing the partition table in Disk Utility. To do that, you select the drive icon, not any of the volume icons nested below it, and click Repair Disk.

Hmm, I followed the suggestion, but it didn't resolve it. I ran Disk Utility reapir off the iMac and there weren't any errors found on the drive. When I switch the GoFlex to the MacBook Pro, it appears in Disk Utility as the main drive, but no mounted partitions yet, same issue. And I can't do any repairs to that drive icon in Disk Utility from the laptop.
Any other ideas?
