I have an external 500 gig WD passport. On my mini, I want it to use upwards of three operating systems (maybe/maybe not at the same). So what file system should I format my external HD with .... Fat32, NTFS, SuperduperPooperFS? I don't want to split up the hard drive into different partitions that that can't be read or written too by one of the other OS.
The operating systems I'm shooting on using are the usual suspects ubuntu, windows (xp/7), and OSX.
I figure OSX doesn't play nicely with NTFS and Windows 7 won't play nicely with anything that isn't fat/ntfs (just my gut feeling, I don't actually know that). So what do you suggest I format my drive as? ....and GO!
