How хан I safetly уменьшает в partition's size?

I have an NTFS partition, with very important восходит on it, of course, and I want to уменьшает its size to поверьте в new partition.

The partition is around 40 % used (60 % free space).

I know we хан использовал GParted to change the size of the partition, but... All of us know that the NTFS system - the naughty problem of "fragmentation", so, we хан not to know where, on the physical surface, the восходи is.

So, my question is:

Does the system "re-alocate" the поля (дата), before to change the partition size (to avoid the risk to lose something)?

Or... I could lose восходит, anyway?
