@bond007fink A new version of ntfs-3g, which is the parent package for ntfsresize, has finally been released last week. That’s after 4 years of no updates. If all goes well, I will be doing an experimental release this weekend with the newer package.
As @Tom-Elliott stated, this is not an issue with FOG itself, instead FOG relies on tools like ntfs-3g and partclone to handle all the NTFS filesystem changes. Hopefully this updated version fixes your issue.
I will update the thread once the experimental release is available.
