Ok, this may be a silly question, as I do not know a whole lot about servers. My goal is to set up a windows server at home, attach an eSATA Raid 5 array (5-1TB) drives, and then put networked home directories for my macs, and roaming profiles for my windows machines. Right now I only have a couple of windows machines (not including the server), and 1 mac, but I am planning to get another mac soon, and eventually transition almost everything to macs. It seems that macs prefer the HFS+ file system and windows prefer NTFS, etc. My understanding is that Macs can read NTFS fine, but can't reliably write to NTFS. Now I know that I can set up sharing between the two using SMB, but my question is what exactly do I format the RAID array in? I assume it is formatted in NTFS, and shared over SMB, but does this then mean that my Macs will be able to read and WRITE to shares on the NTFS formatted file server? As you can see, I have a lot to learn, and I have googled and googled, but I can't seem to find anything that answers this specifically. I read edesignuk's thread on networking windows with OsX, but I am still confused on the whole file system thing... Also, I know that Linux is a good option, and the "server" that I was going to use for a windows, is currently running Linux, and formated in NFS. The reason I want to switch to windows server is that I have a 1-TB NTFS external drive that I could directly attach, and the active directory seems easier to setup than the LDAP in Linux. Still, I haven't ruled it out. Thanks for any insight.
