Hi I had a problem recently with the osx system of my daughter. The SSD disk I built in 1 year ago started to get corrupted file systems. Long boot times (gray progress indicator), failing fck calls have been the result plus at last a system which won’t boot any more. I had no current backup of the system so there was also the problem of the data.
Luckily I had a ccc (carbon copy clone) of my own system. So all you need is the following:
- usb disk/stick with a ccc clone of a working osx
- usb disk/stick for the clone of the broken system
- a little time at your hand
- Boot up the system holding the „shift“ key on startup. Afterwards you will get a list of volumes to boot from, select the ccc clone of your working system.
- When the system is booted open up ccc and create a recovery partition on the destination usb disk you will use for the clone of the broken system, remind to select the matching osx version.
- Clone the entire disk content using ccc from the broken system to your prepared destination usb disk, this may take a while regarding the amount of data you have on your broken system.
- After cloning succeeded, open up disk utility and reformat the disk of the broken system. Remind to check the GUID partition table option and use the journaled HFS filesystem type.
- Now open up ccc again and clone the content from the prior cloned broken system back to the new formatted harddisk of the system. After finishing this, reboot the system.
- Hold down „CMD“ + „R“ to boot into recovery mode. Once there select „Reinstall OSX“, this will again take a little time but afterwards you will be rewarded by a system working the same way as it has before stopping booting. No user data lost, no settings lost, everything is fine.
