mac file server and windows xp?


i just got my new 250gig hd installed in my osx tiger system. i want to be able to dump files from my pc to the 250gig hd (that isent the osx partition hd). the only thing i seem to be able to network to is the user account that is on my osx partition. however i cant see the new hard drive... i know this is probably a stupid question, but is there any way to get files directly to the new hard drive from my xp machine?
