When it's time to optimize my boot drive, I boot up the system from the USB drive and use Drive Genius to optimize the system's hard disk. As one would expect from a product that messed around with the filesystem, Drive Genius presents an ominous warning screen before starting the optimization process. Since my system is backed up using Mac OS X's time machine, my files are backed up to a local file server and really important files are replicated to other machine in my local network, I've blithely ignore those ominous warnings. Although everything has worked out time and again, I guess there's always a first time.Įverything has worked just fine in the past. This time, something unusual happened during the Drive Genius' optimization run. The Mac OS X system update utility unexpectedly kicked in and interrupted the Drive Genius process. As one might expect, interrupting a disk optimization utility is bad. Drive Genius, obviously irritated by the interruption, did quite a number on my hard drive's directory structure. No problem, I thought, I'll just search the internet for suggestions on what to do to fix the disk structure. Since the system was running Mac OS from the USB drive, I first tried the Disk Utility that is part of Mac OS. The utility couldn't verify or repair the disk structure. I tried booting the Snow Leopard installation CD. Then I tried booting the installation disk that came with the system. None of the suggestions I found on various Mac OS forums helped much. ![]()
