Ok, I just committed some more fixes to ntfsresize. It never actually
unmounted the volume, just exited which was very rude of it!
Using the latest ntfsresize/libntfs combination on my Vista data
partition I can now run ntfsresize to change the size of a partition
then immediately run Vista and it boots, runs chkdsk automatically, and
then continues to boot to completion. Yey. (-:
Frans, it would be great if you could verify it is fixed for you when
resizing the system partition also. Assuming you say it works I think
it is time for a new ntfsprogs release which we can rubber stamp as
"Vista compatible". (-:
Best regards,
Anton
