    Unhappy 1 TB HFS+ formatting: EFI?

    Hello!

    I was formatting a 1 TB internal hard drive over SATA-II with "Mac OS X Extended" in Disk Utility. All things went totally normal and the drive works just normal.

    I did later then see in a Ubuntu Livesystem in GParted that my new formatted 1 TB hard drive was splitted in 3 different partitions:

    1. EFI - 300 MB ??? (FAT)
    2. DATA - with the GBs... (HFS+)
    3. 'unformatted' - 170 MB

    So why is there a partition for the EFI, the "Extensible Firmware Interface"?
    Why does Mac OS X needs/installs this on a non-System hard drive? And even more why has this to be 300MB large?

    Why is there an unformatted block of 170MB? Is this normal for 1 TB? Can I change the size of the unformatted block?

    Whats the difference between all the HFS+ filesystems in Disk Utility in detail? Are these all HFS+?
    Which HFS+ filesystem is better for use with Windows (MacDrive): "Mac OS X Extended" or "Mac OS X Extended (case-sensitive)"

    Thanks!

    Default My own Solution!

    So I think this time the saying "there's nothing like doing it yourself" has again demonstrated that it is true:

    Because I didn't want to have this dumb partition combination I helped myself and tried it with MacDrive on windows the program I also want to use.
    So without saying anything it partitioned the hard drive in just one single big HFS+ partition!
    I wouldn't have thought that windows is sometimes good at something again!

    So thanks for the "no-help"!
