One way would be to use a cross over (regular straight through pin out cable will not work) CAT.5. UTP Ethernet cable between the Ethernet ports on each PC (I'm presuming that you have built in Ethernet ports as standard) then share the drive on one of your PC’s. From there you can drag / drop the files at your leisure across your 2 PC peer to peer network using Windows explorer.
Hope that helps.
