Full diskfighter legit1/14/2024 In a worst case scenario, repair efforts might make the disk inaccessible, or fix the directory to the point where it’s empty and all your data is seemingly gone!Ĭome Out and Play - DiskWarrior takes a different approach than other commercial disk utilities. Most of the time, these programs fix whatever problem they identify, but sometimes errors occur, the programs mis-identify a problem, or fix a problem in such a way that it creates others. When these utilities attempt to repair a problem, they write permanent changes to the disk’s directory. Most disk utilities operate in a similar fashion, scanning your hard disk, examining the various directory structures, and making their best guess at what needs to be fixed. (See Geoff Duncan’s "All About Macintosh Extended Format (HFS Plus)" in TidBITS-414 for more details on how Macintosh disks are organized and how HFS Plus volumes work.) These structures have intriguing names like the Master Directory Block, the extents directory, and the ever-popular popular catalog b-tree. These structures are divided into several pieces which record how many blocks are in use, the number of fragments a file has been split into, as well as where each fragment is stored. Just as a table of contents indicates where each chapter and page are located, the Mac’s directory structures track the locations of your files. So here’s the story.Įnter the Warrior - Without diving into HFS, HFS Plus, allocation blocks, or other low-level disk terminology, I like to describe the Mac OS file system’s basic function as being similar to the table of contents in a book. Symantec had updated Norton Utilities to version 4, MicroMat stayed in the fray by adding directory fix-it routines to its TechTool Pro product, and even Apple had pumped up the simplistic Disk First Aid into a more robust tool available for free with the Mac OS.Īfter spending a few months with DiskWarrior, I now understand the product and believe in it. When Alsoft introduced DiskWarrior several months ago (see "Alsoft’s DiskWarrior Combats Directory Damage" in TidBITS-457), I was curious why someone would develop another disk utility program. Nonetheless, disk utilities help ensure your Macintosh runs as it is intended, which in turn enables you to spend more time playing cool games, creating eye-popping graphics, and even balancing your checkbook. There are simply too many cool games, graphics applications, and action-packed accounting programs to tickle your fancy, compared to a small selection of products whose main function is to check the integrity your hard disk – and, after all, you didn’t buy a computer just to spend time maintaining it. If you’re going to get excited about a software application, it probably won’t be about a disk utility program. #1643: New Mac mini and MacBook Pro models, new second-gen HomePod, security-focused OS updates, industry layoffsįighting Corruption with Alsoft’s DiskWarrior.#1644: Explaining Mastodon and the Fediverse, HomePod Software 16.3 and tvOS 16.3, GoTo breach.
