oslomike Posted December 13, 2013 Report Share Posted December 13, 2013 It seems that after restoring a mac os startup disk to an external drive, the disk is unbeatable for some reason. I guess the lock symbol in the corner of the disk icon is a clue. Does anyone know how to unlock this disk or make it so I can boot from it? The restore was otherwise successful as far as I can tell. Any tips? Thanks! mike Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted December 13, 2013 Report Share Posted December 13, 2013 Is the disk partitioned with GUID partition table? Is the disk formatted as Mac OS Extended (journalled)? In the Finder, "Show Info" on the disk, go to permissions at the bottom and set them right. (Check the current boot drive as a guide.)

oslomike Posted December 13, 2013 Author Report Share Posted December 13, 2013 I think it might be tied to the client application was set to read only. Would that make the restore a read only disk? I restored the volume to a disk that has several partitions, all OS extended journaled. mike Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted December 13, 2013 Report Share Posted December 13, 2013 "Read only" on a client only means you are not allowing restores through the client. You didn't answer my first question and it doesn't seem as you tried my suggestion to correct the permissions. Quote Link to comment Share on other sites More sharing options...
oslomike Posted December 13, 2013 Author Report Share Posted December 13, 2013 Hi Lennart! Thanks for the info. I think your suggestion of the permissions seemed to do the trick. I replied at first with what I knew and then went on to try your suggestions. thanks again! mike Quote Link to comment Share on other sites More sharing options...

oslomike Posted December 13, 2013 Author Report Share Posted December 13, 2013 OK. still not able to boot from the restored startup disk. I get an error that the "Building boot caches on boot helper partition failed." The restored disk is a Snow Leopard partition, but the current startup disk is Mountain Lion. Any clues there? Also, I notice that there are two folders in the Snow Leopard disk that have silver locks on them. The folders with locks are called dev and net. Could that also be a clue as to why I cannot startup from this disk? m Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted December 13, 2013 Report Share Posted December 13, 2013 Is the Mac old enough to be able to boot from Snow Leopard at all? Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted December 13, 2013 Report Share Posted December 13, 2013 Try Apple's Disk Utility and "Repair Permissions". Quote Link to comment Share on other sites More sharing options...
oslomike Posted December 13, 2013 Author Report Share Posted December 13, 2013 It took about three hours of the disk utility repairing permissions but it now seems as if it is fixed! Thanks Lennart! mike Quote Link to comment Share on other sites More sharing options...
Lennart_T Posted December 13, 2013 Report Share Posted December 13, 2013 I'm surprised that the restore didn't do this. Retrospect usually says "Finishing restore" when it sets the permissions. This can go on for hours and no progress bar and no estimated time of completion. Anyway, I'm glad it worked. Quote Link to comment Share on other sites More sharing options...
