How about that for turnaround time? Just two days ago Intel announced that it had found the root cause of the power cycle bug that could leave your SSD 320 in a mostly unusable 8MB state. Today Intel is making the firmware available to the public, presumably after a long period of validation testing.
Intel encourages all SSD 320 owners to update to the latest firmware here, even if you haven't encountered the issue. If you have encountered the problem you can either send your drive in for a replacement or secure erase your drive using Intel's SSD Toolbox and then drop the new firmware on it.
As with all firmware updates, approach with caution. While the update shouldn't be destructive, backups are your friend.
