Reboot the Mac and hold the option/alt keys down on the built-in or wired keyboard for OS X's "Startup Manager" there you can select the clone to boot from. Once the clone is finished, use Disk Utility to repair permissions on both drives. while booted from the clone drive if the internal drive fails to boot up.

If you want to maintain a pure clone, then set that in CCC preferences before doing a update, this is what I advise as it maintains space for later less you need to install additional software or move files for data recovery etc. Later when updating the clone it will save the changes between updates and take up much more drive space. You don't need to mess with CCC preferences for the first clone as it has to to everything. Do not use the same name as the internal drive on the external, or change it before you boot from the clone using the Finder. Use CCC to clone your present internal drive to the external. (Optionally is SuperDuper, but it doesn't do the RecoveryHD.)

Later you will use it to update your clone once your on the new internal drive. Secure erase data on a Solid State Drive?ĭownload Carbon Copy Cloner, it's the best cloning software and the only one that also clones the most vital RecoveryHD partition for restoring OS X fresh from Apple. SSD's cannot be securely erased, however it might be possible to overwrite one's preious deleted files with new data with a method I've outlined here.
Physically destroying the drive for the utmost sensitive files. 7x for defeating magnetic recovery techniques. I've found 0x for defeating software recovery techniques, 3x seems to be adequate for mapping off the bad bits. However if shock to the drive occurred or the 0x erase wasn't good enough, or there is unwanted data, then of course repeat scrubbing again. Scrubbing is only for hard drives and not needed if it was done once before as the bad bits were previously mapped off. Once the scrubbing is finished check under Partition that Option: GUID and Format: OS X Extended Journaled or make it that. Highly recommended for all hard drives if it hasn't been done before, SSD's no need. All new drives have bad sectors, this scrubbing will remove most of them and make for a much more reliable backup. If the scrubbing of the drive fails, try again and if it fails, the drive is bad and needs to be exchanged. Warning: Formatting a drive or partition erases all data. 6 users Secure erase Zero all Data) or move the slider for a 0x-3x secure erase (SSD's not needed), OS X Journaled/GUID as the format and a name like "Mac10.6Clone" (different than the internal drive) and click apply. Click on the external drive on the left and click Erase, (10. (say "no" to TimeMachine, use another drive for that). Once the drive is de-Filevaulted it can be cloned.Ĭonnect the new drive to the Mac and open Disk Utility in the Utilities folder.

To de-Filevault your drive will likley require 50% or more free space available to write all the unencrypted bits. If you have Filevault enabled on your boot drive, then this User Tip has no further use for you, sorry. Get a self powered and not a Mac port powered drive! Why? Because Mac's can cut off external hardware drawing too much power which can cause issues trying to boot from the clone. If maintaining a pure clone, then the same size or slightly larger than your primary boot drive will do. If you like the idea of saving the differences between the clone updates, then get a much larger drive. (if so) So later it will be bootable backup (clone) of that new drive. Get a external hard drive equal to or larger than the drive you intend to replace the internal one with. Problems with not enough space for a BootCamp partition and how cloning/reverse cloning can resolve thatīootCamp: "This disc can not be partitioned/impossible to move files." Read this for the differences, advantages and disadvantages of TimeMacine and other backup systems. How cloning/reverse cloning using CCC can defrag and optimize your boot hard drive (SSD's no effect) Create a data recovery/undelete external boot drive If you need to make a new/clean bootable system on a external drive to reverse clone with Made before disaster strikes, it's a real lifesaver!Ĭloning is a bootable backup system, it doesn't fix issues in software It can be used for backup, moving to a larger drive, moving your users to a new Mac (using Migration Assistant), defragmenting and optimizing the system (with reverse clone), shifting data up on hard drives to make more room for BootCamp or another partition (reverse clone) or as a data recovery/undelete boot drive.
