#373 ntfsclone-ng.c: Bad number of free or total clusters after restoring image to smaller disk

Hello experts,

following scenario describes an issue with ntfsclone:

1. Install Windows 10 x64 on a 200GB disk on a virtual Machine, like VMWare / VirtualBox.
2. Take an image with following parameters:
   ocs-sr -q2 -j2 -z1p -i 4096 -sfsck -scs -senc -p choose savedisk test nvme0n1
3. Replace disk with a smaller one, i.e. size of 100GB.
4. Restore image to smaller disk with this command:
   ocs-sr -g auto -e1 auto -e2 -r -icds -j2 -k1 -scr -p choose restoredisk test nvme0n1
5. After successfully restoring the image, take a second image of the smaller disk:
   ocs-sr -q2 -j2 -z1p -i 4096 -sfsck -scs -senc -p choose savedisk test2 nvme0n1
   ntfsclone now is unable to backup the 4th partition of the disk (bad number of free or total clusters). The super block seems to be wrong.

Kind regards,
Patrick

As mentioned here:
https://drbl.org/faq/fine-print.php?path=./2_System/119_larger_to_smaller_disk_restore_clone.faq#119_larger_to_smaller_disk_restore_clone.faq
Clonezilla does not support restoring the image taken from larger disk to a smaller device.
There are some workarounds in the mentioned URL, but not all of them work well.
