Hi all, keep getting this error, I've formatted the drive, its empty, it's a brand new Machine? Image worked fine yesterday on iMacs - I did create the Image on an iMac 5k but can;t see that causing this issue? Built our last image on an iMac and went on the MacBook's fine?
Any ideas? Really frustrating?
Thanks

Is this going to be because I created the image on a 1TB machine and trying ti stick it on a 250GB machine? :/

Yes, and yes yes yes yes yes, Yes.
I use to get hammered all the time by this kind of issue back when drives were going from 80Gig to 160Gig. Because somewhere in there was a drive size threshold being crossed. Essentially a disk image created on say a160Gig drive, even if it only had 5Gig data, could not be used to image an 80Gig drive.
The details go into block sizes (minimum size of a file), and number of blocks on a partition (maximum possible number of files a partition could hold, assuming they are all small enough), and how these figures change, and must change as drives get bigger and bigger. It is the same reason why must USB sticks come formatted as fat32, while most drives come NTFS formatted.
You might want to put the image on a drive it will work with, then use something like Carbon Copy Cloner to clone the disk to a smaller drive, then image the smaller drive.
This is also one of the reasons why we have stopped working with monolithic disk images for deployment, and made more use of Casper Imagings ability to provide a modular approach.

How do you create your DMGs?
Posted on 03-24-2016 06:37 AM
My thought is, if you create your OS DMGs with AutoDMG, it should be fine.
Plus, it's a slam-dunk way to create a non-booted OS DMG.

Recovery>Create New Image From "Macintosh HD"
I always mean to use AutoDMG, but I forget!! I used AutoCasperNBI and always mean to use AutoDMG - lesson learnt, time to create a new image!
So using AutoDMG will irradiate this issue?

Most likely, yes. The only kicker, I believe you have to be on the OS that you're creating.
My suggestion for creating new OS DMGs. (Also my process)

Haha Cheers mate! We do a fat build though (Await being shouted out for not going modular) so I tend to build in app the applications we use! Still goes sit could work the same way! I do need to sue it, and cocked up a little on this base install! So need to re-do anyway!
However it;s bar night at work, and beers are flowing...best hold back!!!

I believe you can add packages to AutoDMG to install into the non-booted OS. I'm not sure though.

You can in fact, add packages to AutoDMG. I'm slowly making my way down this route... i.e. using non-booted OSs instead of booted ones. It will be super awesome when we get there.
