I tried to make a bootable.dmg of one of my hard drives on my main hard drive, but I didn't have enough free space.  I could not find any trace of the attempted .dmg, where that data go?  Where was it stored?

Power Mac G4 (QuickSilver 2002) Dual, Mac OS X (10.4.11), I also use MacOS 9.2.2

    If you wish to make a bootable disk (not image) then do this:

     

    Clone using Restore Option of Disk Utility

     

      1. Open Disk Utility in the Utilities folder.

      2. Select the destination volume from the left side list.

      3. Click on the Restore tab in the DU main window.

      4. Check the box to Erase the Destination.

      5. Select the destination volume from the left side list and drag

           it to the Destination entry field.

      6. Select the source volume from the left side list and drag it to

          the Source entry field.

      7. Double-check you got it right, then click on the Restore button.

     

    Destination means the external backup drive. Source means the internal startup drive.

     

    This will clone the Source volume to the Destination which must be large enough to hold everything on the Source.

    You did not manage to complete your disc image, so none was created.

     

    You did not apparently understand that to image your hard drive onto your hard drive would require free space greater than the total space taken up by all the data on the drive.

     

    Never try to make a bootable disc image like that. Firstly, it requires an enormous amount of space; Secondly, it would not have been bootable. You cannot boot from a disc image file.

     

    You can make a bootable clone as I outlined early. Or, you can install a basic OS X system onto a properly prepared USB drive volume or onto a USB flash drive. You can also create a bootable USB flash drive OS X installer.

    For a g4, you need to boot from a firewire drive.

    Yes, you seem to have it right. At some point the Destination drive needs to be erased.

    If you have moved the data successfully to some place else, then just Erase the drive. This will not be the same as zeroing the drive so it is much faster. You don't need to zero the drive for this operation.
