Physical Domaincontroller (Server 2022) with SSD -> warning "ADDS could not disable the software-based disk write cache..."

Hi community,

I have just added a new physical domaincontroller to my environment (Windows Server 2022 on Dell PE350 with SSD).

I noticed a warning when running dcdiag:

"Active Directory Domain Services could not disable the software-based disk write cache in the following hard disk"

I could not find any best practice for that and on my old Server 2016 domain controller (HDD) there are no such warnings, so I assume it has something to do with the SSD and I'm worried if I could run into trouble...

    It may not be an issue. You might check if your disk and disk controller supports Forced Unit Access
