Using Carbon Copy Cloner, I cloned my hard drive to a new external Western Digital Drive. The WD drive was pre-formatted for Mac and contains Firewire 800 connectors, one of which was used to attach the drive. After cloning, I opened System Preferences and chose the WD drive as the startup disk and selected the Restart button to which the following message appeared:

 

You can’t change the startup disk to the selected disk.

The bless tool was unable to set the current boot disk.

 

What can I do to make this drive become a boot disk? I didn’t see any options in CCC that addressed this situation. The backup was done on a PPC  Mac running OS 10.5.8.

    The WD drive was pre-formatted for Mac

    Open Disk Utility and select the WD drive. In the information provided about the drive, what is listed for "Partition Map"?

    If it says GUID Partition Table", that is your issue.

     

    A PPC Mac can only boot to a drive formatted with the Apple Partition Map (APM). Click the Partition tab in Disk Utility, select 1 (or more, if you wish) partitions, name the partition, in Options, select APM, then click OK and Apply.

    The drive will then be reformatted properly for you to clone to it again

    The Partition Map Scheme is “Apple Partition Map.”

     

    The drive would not boot from either the PPC Mac nor from a MacBook Pro running OS 10.8.

    OK.

     

    I would download SuperDuper! and use it to create your clone.

    The free version of SuperDuper! is fine and the clones are always bootable.

    We don't have the reports of non-bootable clones with SD! like we do with CCC.

    OK, we will erase the drive and do a clone with SD. I'll report back with the result.

     

    What's strange about this, is the user of the PPC Mac has been backing up to a second internal drive using CCC and those backups were bootable. This backup was intended to be a disaster backup to be stored offsite.

    After cloning with SD, the drive still will not boot

     

    It must be the drive. The drive is a Western Digital 2 TB My Book Studio, originally formatted for Mac OS X Leopard, Snow Leopard or Lion.

    The drive is a Western Digital 2 TB My Book Studio

     

    We have lots of negative reports regarding those drives (the chipset of the housing is likely the issue).

    Even the "Mac Edition" doesn't behave like it should......

     

    These housings always behave:

    The 0 GB kit allows you to use any drive of your choosing.

     

    At least we know that it wasn't CCC. Sometimes CCC adds a file or fails to copy (can't recall which) and that makes for a clone that won't boot.

    Thanks for the link. I'm going to write zeros to the WD drive and return it. I ordered the 2 TB, 3 interface drive from OWC. It has a Seagate Barracuda inside, my favorite brand.
