I just recently purchased the Seagate FreeAgent Pro 750 GB USB / eSATA External Hard Drive for my MacBook Pro. I understand that the software that came with it isn't compatible with Mac. I just wanted to know what is the best way for me to set this up because at the moment it's formated as FAT32. Seagate says I should format it to a MAC hard drive for best performance, etc. But there's one problem, I want to be able to share this hard drive throughout the network as I have 4 other Windows PCs connected. Seagate says I should download a program called MacDrive... do I install it on all the windows pc's or something? Or should I do something else? Also how do I share a drive on a Mac? What should I do? I'm new to Mac and external hard drives. Please let me know before I do anything... I appreciate any help. Thanks!!!
