Hi, I recently bought a 640 GB Comstar external hard drive for my macbook, and it came out of the box formatted in NTFS. I know that if the drive was in this format, I could not use it with my mac. So I opened up disk utility and tried to reformat it into Mac OS Extended (Journaled), but disk utility showed an error and the drive wasn't reformatted. So I tried FAT32 instead, and it worked. The drive has been working fine now, however, I have realized a limitation of FAT32: the files can only be smaller than 4 GB. This is a problem for me, so I need some advice. So here is my dilemma: I need to be able to share the contents of the drive over a local network that has both windows and mac computers. (Users on the network only need to be able to read the drive, not necessarily write). However, I can't use FAT32 because of the file size limitation. I'm not sure how to format the drive so that I (using my mac) can read and write it, and users on the local network can read it. I'm thinking HFS+ (mac os extended, journaled), but will windows users be able to read it then? Sorry if I sound like such a newbie. Thanks in advance.
