I have a 1Tb iMac and am trying to restore a Winclone image I created of a windows 10 bootcamp partition. My original bootcamp partition was 450Tb. When I try to restore the image, Winclone states that the required space needed is now 499Tb which is fine because I have 823Gb free.
If I create a bootcamp partition less than 480Gb everything works fine but if I try to create a partition of more than 500Gb I get the error shown above.
I’ve run First Aid, there are no Time Machine instances. I’ve checked in Terminal that there is nothing else occupying the free space.
