Get disk informations without using WMI - powershell

Question

I'm using check_mk as monitoring solution and I disabled WMI service cause it create timeout when check_mk query for information.
Get-WmiObject / Get-Disk / Get-PSDrive use WMI service to get information and I would like to get disk information like total space, used space etc without using WMI beacause I can't.
Do you know any workaround do to that?

TL;DR -
(echo select disk=0 & echo list partition & (for /l %A in (1,1,10) do #echo select disk=next &#echo list partition)) | diskpart | findstr /i /v /r "^$ > microsoft ^reached ^select ^there ^the\ start"
Details -
The 'diskpart.exe' command can get you what you want. It requires admin rights, but since you mentioned disabling services, that didn't sound like an issue.
Rather than interacting with DISKPART's unique menu system, this example will blindly request the list of partitions on the first 11 disks (and filter away unnecessary lines..). Should be enough.

Cmd:
(echo select disk=0 & echo list partition & (for /l %A in (1,1,10) do #echo select disk=next &#echo list partition)) | diskpart | findstr /i /v /r "^$ > microsoft ^reached ^select ^there ^the\ start"
