Hey guys!

So i wanted to make a backup of my 10.9 install before i go installing 10.10 on my hard disk. So what i have done is this:

1.) Bought a 16GB USB, Installed 10.10 here.
2.) Set it up, updated.
3.) Ran Disk Utility to make an encrypted backup of my internal hard disk (Macintosh HD)

Error here! - "Inappropriate IOCTL for device"

I cant seem to create any images whatsoever, Macintosh HD is error free, SMART is verified and the permissions are fine so im a little lost as to whats going on.

Any information and assistance here would be appreciated! :D

You cannot clone the drive if booted into that partition with Disk Utility. You can hold CMD R to boot to the recovery partition (if it is there) and use Disk Utility to restore the drive to an external or use a program like SuperDuper! or Carbon Copy Cloner (CCC).

I wasnt doing that at all, i had booted a USB with 10.10 installed. My goal was to make an image of the internal hard disk (with 10.9 installed). I know you cant make an image of a partition your booted to. (Well, you can but its always empty :p )

I wonder if this has to do with the fact you are booted from a USB device. Does the 10.9 recovery partition allow you to do what you want?

Well i am concluding its 10.10 related. I just erased the USB and installed 10.9 to it and am making an image of the internal HD right now.

Problem resolved.
