My installation on a Quicksilver 2002 running 10.3.9 and sporting an OWC Mercury Extreme 1.4 GHz processor upgrade went smoothly enough, or so it seemed, but when I went to look at the drive with Disk Warrior, I found that the directory was too out of order (29% of files) to fix. I had to clone it to an external drive, then initialize it, re-clone back to it, only to find find that 28% of the files were still out of order in the directory, but that it was fixable with Disk Warrior. Finally got a good directory built. Wasted a good part of an afternoon. But, now everything works smoothly without any discernable glitches. --Steve
