Attempting to Create a system Image would bring up the dialog box, “Where do you want to save the backup” and it would fail with another dialog box with the text:
“Windows could not find backup devices on this computer. The following information might explain why this problem occurred:
Close Windows Backup and try again.”
I searched the Windows Insider Feedback Hub, googled the web and Microsoft forums and I didn’t find a solution until a few days ago. On the Feedback Hub, in a post with the title, “Cannot create System Image in build 18956 FIX IT!“, CJH suggested disabling Windows Sandbox and virtual machine.
After disabling Windows Sandbox (Control Panel/Programs/Turn Windows features on or off/Windows Sandbox) I was able to create a system image again. I initially disabled Hyper-V Manager but after re-enabling it, system image still worked.
In 2012, the MacBook Pro (Retina, 15-inch, Mid 2012) with a 256GB SSD sold for $2399. A speed bump to a 2.6 GHz Core i7 and a larger 512 GB SSD was $3099. That’s $700 for a modest CPU speed bump and an extra 256 GB of storage. I was always constrained for disk space on my MacBook Pro’s 256GB SSD because I use Boot Camp and rEFInd to run macOS betas and Windows 10 Insider Previews.
I knew that my MacBook Pro Retina (Mid 2012) used a proprietary storage drive connector, but until recently, I didn’t know that a standard mSATA drive could be used in it with an adapter.
If you want to use the SSD drive you just removed from your Macbook as a backup drive or other external storage, the easiest solution is to just buy the $59 OWC Envoy Pro case for your SSD.
iFixit has a guide to replacing the SSD in the MacBook Pro 15″ Retina (Mid 2012). It’s a simple five minute process.
Why did I upgrade a seven year old MacBook Pro? My MacBook Pro (Retina, 15-inch, Mid 2012) was one of the first MacBook Pros with a Retina display. I bought it because of the Retina display and the quad core Core i7 (I7-3615QM), The third generation Intel Core processor, “Ivy Bridge,” has a 6MB cache on the CPU.
