Aha, it's time once again to reveal the Disk First Aid secret hidden trick.
After you have selected the disk you want to examine, but before you click on
the start button, do a Command-s (making sure your caps lock key is not down).
It will put up a second window below the first that will give you some of the
details of what it is doing.

I have always found Disk First Aid's "Repair" option to work well; it never
leaves a disk in worse shape than it started. It is not a disk recovery utility
like SUM, however, so for damaged disks you should look at that.

Jim is exactly right about DFA reclaiming free space that was still marked
as allocated. I usually find that running Disk First Aid once a week is a
good way to make sure the HFS data structures on my hard disk are OK. Coupled
with DiskExpress (which is primarily a disk optimization utility, but also has
the capability to examine every block on the disk for read/write errors), you
can make sure your disk is in good shape and optimized for performance.
