 ^^ The 2 digit at the beginning of the line means the pci bus

Use pci-config (apt-get install nictools-pci) to put the nic into
sleep mode

(part of my /etc/network/interfaces)
#              pci-config -B 4 -#1
# gigabyte p35c-ds3r pci bus ^   ^ device number
# The primary network interface
allow-hotplug eth0
iface eth0 inet static
        address 192.168.1.2
        netmask 255.255.255.0
        network 192.168.1.0
        broadcast 192.168.1.255
        gateway 192.168.1.1
        # wol gigabyte p35c-ds3r (on asus p5b I don't need this)
        #pre-up pci-config -W -B 4 -#1 # I don't use
        #pre-up pci-config -B 4 -#1 # I don't use
        pre-down pci-config -S -B 4 -#1 # Put device to sleep (ACPI D3)
        pre-down pci-config -B 4 -#1 # Show the current status



Also, if you share the drive with MS-Windows it may change the status of
the driver.
