>Hex ---- decimal
>Apply HEX(loDrive.SerialNumber) to see the very same number as in GetDriveInformation

Ok, that is what I thought. But, in that version of the code, I was mixing a volume serial number with a drive serial number. So, they had to be different. But, I have adjusted my class and when verifying the same thing, as you said, a conversion would give me the same thing.
