Filesystem fix for laptops
Apple on Monday evening released a filesystem for some owners of its newest laptops. The company said that that the 200K MacBook, MacBook Pro Software Update 1.0 update enables file system journaling on MacBook and MacBook Pro notebook computers, which was inadvertently turned off on some computers: "Some MacBook and MacBook Pro systems were shipped with file system journaling turned off," Apple said in its support pages. "Journaling is recommended on all Mac computers as a preventative measure against file corruption." The update requires Mac OS X 10.4.10 and supports MacBook (13-inch Mid 2007) and MacBook Pro 2.4/2.2GHz Mid 2007) and Apple notes the software will have journaling enabled after the update is installed, but outlines a procedure to startup from the Mac OS X Install or Restore disk to fully repair their startup volume.
Apple recommends closely following the steps below:
1. Insert the Mac OS X Install disc that came with your computer then restart the computer while holding the "C" key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (You must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your internal hard disk drive volume. This is usually Macintosh HD but your internal hard disk drive may have a different name.
6. Click Repair.

people turn it off
Of course, lots of people misguidedly turn journaling off. It really does save you from some types of filesystem corruption, particularly the kinds of things that happen if you suddenly lose power.
Unless you have a specific reason for having it switched off, my advice would be to keep it turned on. The performance difference is (for most people) negligible.
