Clone Hard Drive Mac Os
May 08, 2017 A Mac can be started via a USB port, with a USB key or external hard drive, but that device needs to have Mac OSX system installed on it to boot, as well as other requirements. Best bet is to always backup your Mac hard drive with a bootable image created by Apple Disk Utility or a third party utility such as Carbon Copy Cloner. Sep 30, 2011 I have some problems with my hard drive in my Macbook Pro with Mac OS X Lion. Now I have tried to erase the hard drive to use Time Machine. But I can do nothing with the hard drive. Erasing fails and if I try to install Lion again it says that the hard drive is locked. I even tried to use OS X 10.6 startup disk and erase from there.
