1 TB HFS+ formatting: EFI?
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)"
