In the past, Disk Utility was the best starting point for the vast majority of disk-related tasks.
As technologies within (or possible with) OS X have developed – without equal development of Disk Utility – so it may be useful to have:
- a shortlist of actions that are best attempted/begun without Disk Utility.
I'd like answers to form something like:
- a shortlist of things that appear illogical or impossible in Disk Utility.
I'll seed at least one answer to exemplify what I have in mind.
For some of the things mentioned, there will be answers elsewhere in Stack Exchange – so here, commentary may be minimal.
Maybe more noticeable with Mountain Lion than with Lion:
- some capabilities that are integral to the operating system are misrepresented or impossible within Disk Utility
- some capabilities that are added by third part software are misrepresented within Disk Utility
… and so on.
I'm fairly familiar with routines for HFS Plus and for ZEVO implementations of ZFS. Less familiar with routines for other file systems (both native and not native to OS X).
Recall that features such as Core Storage and FileVault 2 are relatively new, and without native support in Snow Leopard, so let's be gentle in our observations – for any peculiarity, assume that an overriding mantra of 'first do no harm' is applied by Apple.
Beyond this question
A redesign of Disk Utility, by Apple, is desirable but that will be beyond the scope of Ask Different so please: no design suggestions here.
