Mac OS Extended Journaled or not?

In theory it will make the drive more resilient in case of power outages, disconnections, or similar failures. In practice, journaled drives seem to get corrupted just as often as non-journaled. You shouldn't face any problems.

You can use Disk Utility to enable journalling on a drive. It' in the "File" menu. You don't have to reformat.

I found your post searching for a problem I have. I have an ext 2tb drive w pictures and movies. The drive will not allow me to drag and drop to copy files over. It won't let superduper copy files either. The guy who runs superduper said that the drive might not be mac os journaled but fat32. can i simply switch the drive to mac os journeld w disk utility without fear of losing all my data? i need to figure out a way to back up all my stuff and can't figure how to do this, thanks

First of all posting your question at the bottom of thread marked as solved is not the best way to get it noticed.

To answer your question, no you can't. In order to change from FAT to HFS, it will be necessary to reformat. The reformat will destroy everything on the disk. So anything you what had better be backed up prior to starting the reformat.
