Question: HFS+ hard disk format

I just upgraded my macbrook pro to snow Leapord and I was going to get Word and install it. I was reading the specs and it says I need HFS+ hard disk formating.


does that mean I have to go into utilities and reformat my entire drive and reinstall every thing? What the the deal with HFS+ any way?

MacBook Pro, Mac OS X (10.6.3)

It is recommened you use Mac OS Extended (Journaled). Both that and non-journaled are HFS+. But it is usually recommended to have Journaled for better disk fault recovery. But the disks will work even if not journaled.

About file system journaling


Stop reading microsoft specs and just try to install Office.

Mac OS Extended = HFS+

Mac OS Extended (Journaled) = JHFS+, or, in common parlance, just HFS+

(HFS = Hierarchical File System)


HFS+ has been the default file system on the Mac since about System 8; that is, to be very precise, for donkey's years. It is possible to install Mac OS X on different file systems, which why MS specifies HFS+, but that's only for techies. For the purposes of installing and using Word, it doesn't matter if it is journaled or not, but the former has been the default since Panther or Tiger, I can't remember which.

Since we know that Mac OS Extended starts from HFS+ as the base, your job is done and the disk was already ready for Word (and most Mac software)

"Mac OS Extended" is just another name for HFS+.


Kurt Lang:


do not format a drive as case sensitive.


This is HFSX, or "Mac OS Extended (Journaled, Case-Sensitive)"; it can be regarded either as an extension of HFS+, or a different HFS+-based file system (HFS and HFS+ are case-insensitive). It is sometimes required, but, basically, if you have to ask what HFSX means, you don't need it. Unless you know what you are doing and why, just go with the default offered by Disk Utility.
