get disk space info incorrect on windows

[rustbomber]

on some machine, my disk total space is 5TB and use code, some partition total space is incorrect

let total_space = disk.get_total_space();
let available_space = disk.get_available_space();
let used_space = (disk.get_total_space() - disk.get_available_space());

but D/E/F partition total is 5785851133440.

[

      "total_space": 214745610240,

I also use golang test, with package github.com/shirou/gopsutil/v3, is report correct:

Thanks for reporting the issue! Maybe @mjarkk would be interested into taking a look? :smiley:

[mjarkk]

I'll check it out.
@akaylh Is it true D, E and F are one disk with 3 partitions because the partitions seem to fit into 5785851133440?

[GuillaumeGomez]

Awesome! Thanks a lot!

yes, my server have two disk in fact:

Ah this also explains then why your C disk in this library is bigger than gopsutil.

I think the problem should not be here, mainly because the total space of D/E/F is incorrect 。

BTW：My English is a weak！

I've created a pr to fix this #431
