Format-Volume : No matching MSFT_Volume objects found by CIM query for enumerating instances of the
ROOT/Microsoft/Windows/Storage/MSFT_Volume class on the  CIM server, that are associated with the following instance:
MSFT_Partition (DiskId = "\\?\scsi#disk&ven_corsair&prod_cssd-f12..., Offset = 403701760). Verify query parameters and
retry.

CODE:
New-Partition -DiskNumber 0 -Size 260MB -GptType '{c12a7328-f81f-11d2-ba4b-00a0c93ec93b}'
$Partition2 = Get-Partition -DiskNumber 0 -PartitionNumber 2
Set-Partition -NewDriveLetter S -InputObject $Partition2
Format-Volume -FileSystem FAT32 -Partition $Partition2 -Confirm:$false
Change from gpt type PARTITION_SYSTEM_GUID to PARTITION_BASIC_DATA_GUID or PARTITION_MSFT_RECOVERY_GUID works ok for format, but looses 'system' reservation.
Only apparent way to fix this is by setting PARTITION_BASIC_DATA_GUID and then via DISKPART SET ID...
I've tried several ways to pass a valid input parameter through to -Partition for Format-Volume, but it keeps trying to interpret it as an InputObject of type Volume.  It's impossible to get a Volume Object for the new partition when it doesn't exist
yet, but Format-Volume is refusing to accept this partition gpt type as valid input.

Hi Tsw,
Yes, based on my research, the best way to format the system EFI partition seems using the cmd "diskpart":
$sysPart = New-Partition -DiskNumber $disknumber -GptType '{c12a7328-f81f-11d2-ba4b-00a0c93ec93b}' -Size 100MB
$systemNumber = $sysPart.partitionNumber
select disk $disknumber
select partition $systemNumber
format quick fs=fat32 label=System
exit
@" | diskpart
