Over the years, I've consistently found Disk Warrior to be the most reliable Mac drive utility. It has repeatedly been able to repair issues that Disk Utility cannot. I recently had a hard drive crash that Disk Utility was unable to repair. Disk Warrior correctly diagnosed a hardware malfunction and even though it was unable to create a new directory on the drive, it created and mounted a temporary one in RAM that allowed me to extract all the data I needed off the drive before returning it for a replacement. I would offer this comment: if a hard drive's directories are damaged enough that Disk Utility cannot repair them, there is an increased likelihood that the drive itself is experiencing problems. I strongly suggest the following procedure: use Disk Warrior to repair the directories, back up all the data to another drive, completely reformat the drive and run diagnostics to be sure that it otherwise appears OK, and then make sure you have a regular backup so that if there is a mechanical problem you are covered. My two main drives are Western Digital 500GB, one a standard drive, the other an "Enterprise/Server Class" drive with much higher MTBF rating and a five year warranty. Interestingly, it was the Enterprise Class" drive that failed and had to be replaced.
