Mac OS-X disk file format I need to format an external hard disk on a MacBook Pro (USB2 connection).
In the disk utility, Erase tab, I can only choose between these formats:


MacOS Extended (Journaled)  
MacOS Extended (Case-sensitive, Journaled)  
MS-DOS (FAT)  
ExFAT  


I do not get the following options, which should be available:


MacOS Extended  
MacOS Extended (Case-sensitive)  


OS-X version: Lion 10.7.5

Reason: it seems that an unjournaled MacOS disk is accessible from Linux and Windows.
Unless you have a very good reason to choose otherwise, it is highly recommended to use a journaling file system to ensure data integrity. In the case of Lion and Mountain Lion, the default is MacOS Extended (Journaled). Case-sensitivity at the disk level can mess with certain apps, and the OS makes it look like files are indeed case-sensitive when you interact with them on the command line.
