Your original question, based on the title was formatting a HD for Windows XP. Hence the response you got.
To your question of HFS+ vs HFS+ journaled, journalling was added in Panther and later versions of OS X. With journalling, the file system becomes more robust towards crashes, because the file system keeps track of changes made to the file, called journals. If a crash occurs, the damage can be repaired by replaying the journals to get the file system back to the original undamaged state.
