No need for formatting when you switch to ext3. Just do a tune2fs -j /dev/your_data_drive, change the ext2 to ext3 in fstab, remount and voila.

Check man tune2fs (esp the -J option) for journaling parameters.

Should mention that this should be done in single user mode. That's safest. Otherwise, just make sure to unmount the partition before changing it to ext3. No formatting needed. ext3 is ext2 with journaling. In fact, old kernels can still read ext3 partitions as ext2.

As in runlevel 1. Type init 1 (as root) and you'll get there. Actually sans-hubris is right about that one. You should probably go down to runlevel 1, however, I was nasty enough to convert all my partitions to ext3 without unmounting them nor going to single user mode and it worked flawlessly ;)
