How can I disable journaling in El Capitan?

I just tried it on 10.11.1. I didn't have any problems disabling and enabling journaling on a flash drive and on a mounted and active Macintosh HD of a test system. I was logged in with an admin account and didn't have to use sudo. A simple "diskutil disableJournal /dev/disk0s2" worked as expected.

Have you specified a volume? It won't work with a disk.

Are you receiving an error message when trying to perform the task?

Have you checked that the volume is actually using journaling?

Have you tried the force option of diskutil disableJournal?

May I ask why you want to disable journaling? I ask because I would on a journaled file system (NOT Apple's, rather for Linux, Solaris, AIX) and I would like to understand the benefit of trading no journaling for very long fsck_hfs run-time after a system crash?

How about running Linux is a virtual machine?

VMware Fusion

Parallels

VirtualBox

Im having a similar issue with not able to disable journaling with clicking file & option key. I have tried through terminal diskutil disablejournal also with sudo as well. This is the message i get when using terminal.

Usage: diskutil disableJournal [force] MountPoint|DiskIdentifier|DeviceNode

Disable journaling on an HFS Extended volume. The volume will be

temporarily mounted if necessary, so normally this works whether or not the

volume is mounted. The force option, however, causes a direct write to the

on-disk volume data, and requires that the volume not be mounted.

I want to disable it temporary to scan computer with fixmestick.

I Appreciate The Support.

A message like that indicates that you have mistyped the arguments to the command. You got the command itself correct, but you didn't supply the information it expected in the arguments.

You didn't indicate what your command was, but I'm not sure I could readily figure out what was wrong with your arguments.

In the terminal application, type :

1) List the partitions

diskutil list

2) Disable the partitions

diskutil disableJournal /dev/disk0s1 + [Enter]

diskutil disableJournal /dev/disk0s2 + [Enter]

diskutil disableJournal /dev/disk0s3 + [Enter]

diskutil disableJournal /dev/disk0s4 + [Enter]

Reboot with fixmestick

I've tried things said by jmfromanderlecht. Here is a screen shot or what i have tried in terminal from before and with the suggestions.

/dev/disk0s1

/dev/disk0s2

/dev/disk0s3

etc....

NOT "Macintosh HD"

And on the command line white space is an argument separator. So even if "Macintosh HD" was correct (which it isn't), you have to protect the the spaces from being seen argument separators.

I tried what you suggested diskutil disableJournal /dev/disk0s2 + [Enter] and the is the message that i get.

Ownership of the affected disk is required.

Also do you know a way to reenable so i can just enable and disable journal with the disk utility app instead of terminal.

Ok, you're not supposed to type the words, "+ [Enter]"

He just meant to hit the return (or enter) key on the keyboard.

And, you don't even need the /dev/ part. Just this:

diskutil disableJournal disk0s2

In the future, don't bother trying to type in what you entered and what the response was. Just copy the whole thing from the line where you enter the command until the end of the response. Then, just paste that text into a reply here. We then don't have to guess at what you really typed as we'll be able to see it.

As you can see, this is why playing in the Terminal can be hazardous. If any of those partial commands you tried would have done something disastrous, you would have been SOL.

i put what you said and i received this message. An error occurred journaling the file system: This operation requires a disk that contains a file system (-69829)

do you no how to reenable disable journaling with the disk utility app.

Thank You all for your help i just double checked over the diskutil list and i chose the wrong identifier disk0s2 and my drive identifier was disk1 and now my hard drive is not journaled.
