You must be doing something else.
This app shows only one more handle after CreateFile.
And it goes away after DeleteHandle.
Do you have PE set to show all of the handle details?

#include	"windows.h"
#include	<conio.h>

void pause(void)
{	cputs( "\r\nCheck for number of handles, then press any key");
	getch();
}

int main(void)
{	HANDLE		h;
	DWORD		written;
	char		str[1024];

	pause();
	h = CreateFile( "\\\\.\\PHYSICALDRIVE0",
                         GENERIC_READ,
                         FILE_SHARE_READ | FILE_SHARE_WRITE,
                         NULL,
                         OPEN_EXISTING,
                         0,
                         0);
	if(INVALID_HANDLE_VALUE!=h)
	{
		pause();
		SetFilePointer(h,0,NULL,FILE_BEGIN);
		pause();
		ReadFile(h,str,sizeof(str), &written,0);
		pause();
		CloseHandle(h);
		pause();
	};
	return 0;
}
