Issues Creating a Bootable Hard Disk Clone in Mac OS Mojave
Posted on: 12th May 2019 by Mark Tiddy
Recently I needed to add some more storage to my 2012 MacBook and so I picked up a whopping 2TB hard drive from Crucial…cloning drives isn’t something I’m new too…in fact, I already have Carbon Copy Cloner on my Mac which I use to create a bootable backup regularly and I installed a 1TB SSD in my MacBook a few years ago (which I’ve filled up…hence a new drive!).
I already owned a USB hard drive docking station and so plugged in the new drive to that, formatted it to APFS (the same format as my existing drive running Mojave) and then cloned my existing drive to the new drive in Carbon Copy Cloner.
Then the problems started…
I went to boot it via USB to check the clone had worked and was presented with this…
So, wondering if USB simply couldn’t handle it I went ahead and installed the drive into my MacBook Pro and went to boot it up and was presented (after it got halfway through the boot cycle) with a no entry sign.
So I tried reformatting it and then cloning again using Carbon Copy Cloner with the same results.
The help pages of CCC and google didn’t help me solve my issue so I reformatted again and tried the restore mode of data transfer using Recovery Mode.
This time, after a day of ‘restoring’ using disk utility in Recovery Mode it presented me with an error after verifying that read ‘Status Error 22’ (at least it was a new error!).
This time I found people on Google having the same issue as me but running different versions of Mojave (or even older versions of Mac OS) but no solutions.
I had three choices: I could assume the drive was faulty and contact crucial, I could assume there was a problem with my existing drive and go down the route of a clean install and then restoring via Time Machine or I could try a different way of connecting the drive…so for £6 I picked up this USB 3 USB to SATA cable off Amazon and tried my Carbon Copy Clone again (this time it look 3 hours rather than 16 thanks to USB 3 over 2!) and it worked!
I thought I’d write this post just in case anyone else has had the same issue and hope it helps someone out!
