I've got a windows based wireless network aroun d the home. I'm using a MBP and have an externl HD. the problem is i move about with my mac, so I'd like to make the HD wireless using either airport express or extreme. the question is does express cater for ard drives? or is it only a booster/audio signal transferer. one last questions, can I connect to my home network and the HD at the same time? thanks.
