Disk Warrior Rescues the Post-Lion Upgrade Blues
If you’ve installed Lion as an upgrade over your Snow Leopard install, you may want to run Alsoft’s Disk Warrior 4.3 (now available for download) to investigate whether any directory tree damage may have resulted from the install.
After installing Lion over top of my Snow Leopard install, Disk Warrior reported a staggering 25% directory fragmentation.
Based on its reporting, I elected to have Disk Warrior to generate a replacement directory tree structure to overwrite the existing fragmented version.
Finally, here’s the Before and After results of running Disk Warrior. A fresh directory tree structure minimizes the likelihood of data corruption and improves performance. Once again, Disk Warrior has proven itself to be an indispensable part of my Mac utility arsenal.
NOTE: You need to have a copy of Disk Warrior 4.3 for it to run on Lion. If you’ve purchased version 4.0, 4.1, or 4.2, you may download the update for free via Alsoft’s website.

July 24, 2011 at 7:07 pmNo, DiskWarrior’s good. It creates an optimized directory. Upgrading to Lion scrambled the directory structure on my new MacBook Pro. I’m waiting on a Firewire 800 to FW 800 cable so I can use DiskWarrior through Target Disk Mode because the FW disk I have won’t boot the new Mac.
