Drive is plugged in. fd0 enumeration is not fixed. From devinfo:

    fdc0 pnpinfo _HID=PNP0700 _UID=0 at handle=\_SB_.PCI0.LPC0.FDC_
        Interrupt request lines:
            0x6
        DMA request lines:
            2
        I/O ports:
            0x3f0-0x3f5
            0x3f7
      fd4
    unknown pnpinfo _HID=none _UID=0 at handle=\_SB_.PCI0.LPC0.FDC_.FDD_

                Device (FDC)
                {
                    Name (_HID, EisaId ("PNP0700"))
                    Name (MCD, 0x11)

                    Device (FDD)
                    {
