Meaning of "Owners Enabled"??

I recently added new drive to my Mac Pro. While I was doing drive setup in Disk Utility I noticed that in the information about the drives at the bottom of the window, it stated that the main Macintosh HD was "Owners Enabled : Yes" and the other three internal drives and the two external firewire drives were all "Owners Enabled : No."
What does this mean? How do I change it if I need to?

Mac Pro DUal Quad Core, Mac OS X (10.6.4), Early 2008

I appreciate your time in responding to my question, but it still hasn't clarified the issue.
I have read other posts that refer to "Get Info" on drives or directories, and also mentions of "Ignore ownership..." but they were equally confusing.
I'm still looking for a clear definition of what it means, how does it affect me, does it allow others to read or write files, which is more secure, does it have anything to do with a disk being journaled or not???

Nope.

I would pick up a book. Or spend time looking up Unix features via Google, as well as Help. Don't have Pogue's "Mac OS X: The Missing Manual" might consider that too.

When you look at Get Info on a boot drive, for it to be bootable, the flag for "Ignore Ownership" has to be off.

If you were to clone a drive with the flag set (Ignore Ownership) it won't boot.

Take a look with BATCHMOD and see what it shows.

Chmod is a Cocoa utility for manipulating file and folder privileges in Mac OS X (10.5 recommended). It allows the manipulation of ownership as well as the privileges associated to the Owner, Group or others. Here are some of the characteristics of BatChmod:

It's simple and elegant
It allows one to change any specific privilege or ownership without affecting the others (ie, changing the group without affecting the owner, or adding or removing a specific privilege without affecting all the others)

Also, from homepage:

BatChmod is a utility for manipulating file and folder privileges in Mac OS X.

It allows the manipulation of ownership as well as the privileges associated to the Owner, Group or others. It can also unlock files in order to apply those privileges and finally, it can remove any ACLs added to a folder or file under Mac OS X 10.5 Leopard if required.

+If none of this makes sense to you, maybe BatChmod is not for you :-)+

It has the potential to mangle your files if you do not know what you are doing. ESPECIALLY if you change the permission of your whole disk at once... just don’t do that.
