I have a Macbook and bought a 750GB Iomega external HD. I originally used the HD with my Macbook and put a lot of files on there. When beginning it never asked me to format the drive or what type of formatting to use. I recently got my PC working again running Windows XP SP3 and I want to transfer the files onto that computer for use. When I plug in the HD it is recognized and is in device manager. It is not assigned a drive letter however, Windows says the entire HD is unallocated. Any way to get files onto XP machine without moving them all somewhere else? I don't have another HD big enough to hold them all at one time besides my PC.
