    Greetings


    I've recently bought a 1.5 TB My Book Essential external hard drive to back up some data and also to transfer in/out different devices at home.

    So I have a few questions:

    1.- As I expected, OS X told me that it couldn't write to the disk, since the format isn't compatible. This is no problem, as I will be dividing the disk into 2 partitions, and formatting each one, one for my Windows machine, in FAT32 or NTFS, and one for my Mac. Now here's the thing - What format do I choose for the Mac partition? I have several options and don't know which one to choose.

    2.- I'm considering to use the drive as an "official" Time Machine drive, instead of just copying files onto it. Now here's the question - How do I make it so instead of it just making different versions of my backup, to it to replace the previous backup each time I do it, so I don't end up with the whole space filled up? I don't need different versions of my backup, I don't do that important work.


    Your sincerely,


    ramzhh.

    2) Partition your drive and only give TM enough space to save one or two backups.

    1. "Mac OS Extended (Journaled)", though "Mac OS Extended" works too and is preferable with some external HDD use like video editing.
    Maybe GGJstudios will post his file system FAQ, as I currently don't have access to my TE library.

    2. You could also use CarbonCopyCloner or SuperDuper to make a bootable backup, which will not accumulate past versions of your files.
