Hi, I am relativly new to Mac and have been trying to set up a network between a PC (running Windows 7) our iMac and an external hard drive. Currently we have the external hard drive (formatted to Fat32) connected via usb to the imac, the iMac is connected to our modem/router via ethanet. The pc is also connected to the modum/router via ethanet (to access internet). I have set up file shargin on both windows and mac with read/write permissions. Heres the problem.. the pc can see, and access the external hard drive, it can open existing documents from the external and save these existing documents back to the external once they have been modified. However if we start a new document in say Word and they try to save it to the external hard drive it will not allow this document to save. Any help would be appreciated and thanks!!
