This then gave me four startup disk icons: I then shutdown and rebooted with the Option key. It offered either my main drive or the Super Duper clone. This opened with a dialogue box offering four choices:Īmong the items on the menu bar was "Startup Disk". Instead of seeing my main drive icon and the SD clone icon, I had the main drive icon with another drive icon called 10.8.5 Recovery. I shutdown and rebooted holding down the Option key. Things did not go as I would have expected. Your post got me to check how my Super Duper clone is working (SD 2.8 (v96)). I am an earlier OS (10.8.5), but my Super Duper backup is also on a Hitachi drive in an OWC Mercury enclosure (320GB HGST Travelstar Z7K320 2.5-inch 7mm SATA), although I am connected by Firewire 800.
Is there any way to test the enclosure?ĪDDENDUM: When attempting to boot fro the clone, the progress bar goes about half way, stops, and the computer spontaneously shuts down. I feel that the hard drive is unlikely as the source of the issue because it is checked daily by Check Mate, with no problems found (file structure test, SMART, surface scan). I tried reconnecting via USB 3 but that was unsuccessful.Īt this point, I think that the problem may lie with either the enclosure or the hard drive. I have the enclosure connected via Thunderbolt. Disk Warrior reports minor issues (incorrect root correction date and repair of a custom flag for ScamZapper) but I have not run DW on the clone after re-doing the clone. The clone did boot, once, after running Repair Disk via Disk Utility but I think that that was coincidence.

Erase the clone and re-clone from scratch. He had me try the following (all unsuccessful):ġ. I contacted Dave Nanian at Shirt Pocket (the developer of SuperDuper) and he has not seen this issue with El Capitan. After upgrading from Yosemite to El Capitan, the clone will not boot (although this may be coincidental).
The clone is located in a Mercury enclosure on a Hitachi DeskStar 2 TB drive. I use the latest version of SuperDuper to make a clone.
