NTFS file system (Windows) with cluster size ≥ 64K

Are you folks familiar with "NTFS file system (Windows) with cluster size ≥ 64K"?

Since when is that happening?
Are there MS sites telling about it with details?

Lots of questions.
Like: which kind of programs might be effected by this?

I know that Advanced Diskinfoscope (ADinf32) released fixes for this last month.
See the ADinf32 Changelog
https://www.adinf.com/en/faq/changelog.php
v2.04.0000/Gen2 12/17/2022
v2.03.0000/Gen2 12/11/2022

I happen to know that more program(s) need to be upgraded for this.
No, I cannot give more info. That is up to the companie(s).

As I said: lots of questions.
Which kind of programs might be effected by this?
Only the low-level programs?
Maybe the system backup/restores programs?

 

It begins when you format a partition (file system creation).

 

Thank you @stapp for that link

I have to admit that the recent patches for ADinf32 raised a lot of questions for me and that I never had to bother about cluster sizes (well, I guess that is clear from my newbie post about it).

The first picture in that article ( ntfs-cluster-size-1.png ) makes it clear that there are much larger cluster sizes than 64K possible.
It raises the question: didn't the ADinf32 developper know that? Or maybe ADinf32 wasn't used before on systems with such larger cluster sizes? From what I understood from him, it was new for him; that can happen. I will send him the link you gave.

Thanks again!

 

OK.

 

windows 10 is able to create 2M cluster. (x64)

GPT, 4K cluster -> 15TB max. i dont see any problem.

 

You have to stick with 4k if you want to use compression. Which I doubt too many care about these days.
