Hi, I have a hard drive in one of the bays on my early 2008 Mac Pro that is formatted to ‘Mac OS Extended’ this hard disk contains my itunes library. I want to reformat the drive to ‘Mac OS Extended - Journaled’ Can I do this without losing all the existing files? Or should I make a copy, erase the drive then copy the files back onto the new journaled drive?
You aren't reformatting. But I would always always no matter what clone my system and have two or three backup sets and different types for redundancy. Bootable backup clones are easy to maintain and handy, say 10.;8.5 didn't go right, or you want to hold off on iTunes 11.1 or even test it on another system drive first. Clone has many good uses.
To turn journaling on and off using Disk Utility:
Note: In Mac OS X 10.4 and later, press Option to make Disable Journaling visible in the File menu.
