Journaled file systems are much more resilient in the face of sudden power failures and they also recover a lot faster if corruption does occur. Basically, they keep a copy of every write transaction in an on disk record keeping area called a journal. If the disk dies in the middle of a transaction, and that transaction is still marked as open in the journal, recovery is usually as simple as "replaying" the journal entry. MUCH faster than scanning the ENTIRE disk for possible corruption. With a journalled system, the Mac knows exactly what it was up to when the lights went out and can zero right in on it to detect and repair any possible damage. You chose the right one!</blockquote>
