I've got a Powermac G4. It's effectively just my home server pretty much. It is hooked up my Seagate Freeagent FW400 external hard drive. It shares this very nicely with other Macs on my network. But I'd also like to be able to share the files(movies, music, and software archives) with the 3 or 4 PCs that are also on my network. Right now, it's formatted for Mac, HFS if I remember correctly. So what format can I use that I can read and write to under OS X, but also under Windows? I had it FAT32, and that worked well, until A. My other Mac couldn't see it over the network, and B. I tried putting a 5GB file on it. So is this possible without 3rd party utilities? I have Macdrive installed on XP on my Bootcamp partition, but it won't "map network drive" - I take it Macdrive doesn't work for network drives. Any ideas? Thanks in advance!
