I am currently running Windows 7 64-bit on my MacBook Pro with read/write access both ways. But whenever I start a torrent download on my Mac side (using Transmission) then start up Windows and add the torrent file to uTorrent to continue the download, it doesn't check the data I already downloaded and starts from scratch! 
Please tell me how I can have uTorrent on my Windows side read the already downloaded data correctly so it'll CONTINUE the download from my Mac side rather than START OVER.
