there is a format for a hard drive that both mac and windows OS can read/write to? I want an external hard drive that stores files they can both read/write, and use for backups, etc.

this question has been asked several times before. see superuser.com/questions/47257/… or superuser.com/questions/72546/… or... (can anyone else find a better "duplicate"?) – quack quixote Jun 7 '10 at 1:37

FAT-32 is the best option since it works with all OS. NTFS has drivers available so you should also be able to use it with linux mac and windows. HFS would be poor choice. FAT-32 cannot handle files greater than 4 GB though

FAT32 is the most supported, but it's biggest flaw is that it doesn't support large files (> ~4 GiB). Next would probably be NTFS, supported (albeit not perfectly) on Mac by default (I think). Next would be HFS+, the native file system for Mac OS, but not technically supported on Windows by default. (Unless you call playing with mounting, drivers, and such "default").

In short, go with FAT32 if all files < 4 GB, otherwise NTFS.
