Cannot make a disk image with disk utility Status 27 I'm trying to take a disk image of a MacBook Pro 2012 with an SSD and OS X El Capitan installed.
I went into Recovery Mode and selected my partition and the target is an external HDD.

First I got error status 2, but then I remembered to unlock the drive. 
Now I get error status 27, I searched a lot to find about this error, but couldn't find the meaning of the error.

I want to take a full backup, reinstall a fresh OS X and then later I will format it again and restore my old system from the image.



Edit:
I now tried to take an image only of the user folder and got operation failed with status 107.

Any help would be appreciated.
The Format of the partition must be Journaled to be able to make an image
