Three years from the last update, is it really worth the wait?
DiskWarrior 5 is the latest release of a revered Mac utility dating back to the late ‘90s. The software repairs and rebuilds damaged disk directories, the roadmap computers use to find files and folders scattered across all of those platters. Optimised, errorfree directories provide faster file access, fewer spinning beach balls and a more pleasant experience.
Three years after the last major release, DW5 features a streamlined UI and finally delivers 64-bit support, which enables tackling the larger disk directories found on more voluminous modern drives. A new Directory Optimization Index provides a visual graph of disk efficiency even before clicking the Rebuild button.
Version 5.0 ships on a bootable USB flash drive instead of CD or DVD, which makes sense but may be a minor nuisance for upgraders. But that’s where the bad news ends.
The thumb drive is capable of repairing the startup disk of Intelbased Macs that originally shipped with OS X 10.4 through 10.6, and can be upgraded for OS X 10.7 and later using the included DiskWarrior Recovery Maker.
Alsoft claims rebuilds are now twice as fast, and we noticed an immediate and real performance difference in our tests with a mid2004 Power Mac G5, mid-2007 Mac mini and mid-2012 MacBook Pro with Retina Display. DW5 also feels more stable compared to earlier versions that would often consume excessive CPU time and occasionally even crash. JR Bookwalter
DiskWarrior 5 remains a musthave disk utility, and is more flexible than ever on a USB thumb drive.
Helpfully, DiskWarrior 5 now shows a Directory Optimization Index that displays information about what condition the selected drive is in before rebuilding.
