On a Catalina 10.15.2 system, when trying to image a Bootcamp volume, Winclone 8.01 runs through its sequence and reports “Image saved” after about 30 seconds. Winclone image file size is 674 bytes!!! (Obviously, it did nothing. Boot camp volume size is 299 GB.)) Rebooted after granting full disk access but same behavior.
Have a Mojave volume with Wiinclone 7 installed. Booted into it and tried it with Winclone 7. Same behavior. This Bootcamp installation is from a restored Bootcamp image using Winclone 7. So, it looks like both versions are having trouble reading the restored volume and both versions are temporarily impotent.
