DeviceName for created storage unit #11

Hello.
This is probably more question than issue.
I created in my project SpdStorageUnit and I can use it after format. I would like to format it myself (in C++) but I can't find any way how to find new disk or volume that was just created by WinSpd. I can enumerate volumes before storage unit is created and again after it's created - new one will be the one I am searching for. I am just looking for proper way using WinSpd API.
I found SpdIoctlGetDevicePath but it doesn't give me correct path, just prefix. I set ClassGuid to SPD_STORAGE_UNIT_PARAMS.Guid and DeviceName to nullptr.
Is there any way how to find \Device\Harddisk... for created Spd storage unit? Thanks.

I solved this (for now) by searching for SPD_STORAGE_UNIT_PARAMS::ProductId in VDS_DISK_PROP::pwszFriendlyName. Then I enumerate all volumes and search for mine by disk number.
