okay on whim shrunk 10 gb , worked. did 4 more times , have 50 gb ntfs drive, issue solved. thanks.

right click partition want resize first try "unmount". after should able resize partition.

for issue: partition trying resize needs fixed first. says on error message please. should able resize after fixing file system.
