A perfect Save and Restore with one tiny hitch
 

SD just saved my ass with a nearly perfect restore of my regularly scheduled back-up of my Mac Pro's raid. It took a while to load the data back on from the external FW800 back-up but it did so with no issue.

The one problem is that I had set the restore to set the raid as the start-up disk. It did so but the machine did not correctly boot into the OS from the restored Raid. It hung and then got the "No Apple" emblem above the gear.

I booted flawless from the back-up, set the start up disk manually in prefs after re-verifying all aspects of the raid and restored data. The machine then booted perfectly upon restart.

Any Ideas what might have happened?

So, you didn't get any kind of error? Tiger or Leopard?
