This is done by some Windows component between Win32 API function 
kernel32.dll:CreateFileA() (called by smartctl) and NT-Kernel function 
ntdll.dll:NtCreateFile() (called internally by CreateFileA).

Tools like sysinternals procmon use some internal Windows Layer and 
therefore do NOT necessarily log the actual system calls done by the 
program.

Example: 'smartctl ... /dev/sdb' calls Win32 API function:

    CreateFileA("\\\\.\\PhysicalDrive1", ...);

Procmon logs:

    ... CreateFile    \Device\Harddisk1\DR1  ...

or with "Filter -> Enable Advanced Output":

   ... IRP_MJ_CREATE    \Device\Harddisk3\DR3    ...
