Casey (Surname withheld for contractual and professional reasons) has contributed many great articles on thetechmentor.com. He successfully started his own IT consultancy well over 10 years ago.
While going through this tough yet rewarding experience he found there was a terrible lack of focused support out there for computer techs to start their own IT company. So he gravitated towards training and mentoring other computer technicians who want to create a part time or full time income as an IT consultant. He initially wrote thetechmentor.com courses to help computer technicians start their own IT consulting business (or side business). Many articles also help the general public save thousands of dollars in professional help by helping them DIY. He doesn't contribute directly to thetechmentor.com often any more due to leading a full family life and being Technical Director a at major US company (hence the requirement for privacy).
However his contributions span over 10 years and some have been extremely popular (with so many comments we had to stop accepting more on some, and thousands of shares although it looks fewer after our change to https - we must get around to fixing that!). Having said this, we work to ensure his work is updated and continues to remain relevant.
Background I've been using the $119 DiskWarrior to perform routine maintenance and to resurrect defunct Macs since it shipped on a CD. While Alsoft has updated the utility and adopted flash storage over the past 18 years, DiskWarrior continues to perform maintenance and recovery tasks that no other utility can do. That includes utilities from Apple, whose Disk Utility may be suitable for basic maintenance and partition, but remains ill-prepared to repair badly damaged directories that result in kernel panics and boot failures. While can scan disks to recover lost or deleted files, DiskWarrior is unrivaled in its ability to repair and rebuild the Mac directory. It's worth the price of admission. As a senior Alsoft technician explained it, Apple's file system (HFS+) is a complicated animal.
DiskWarrior rebuilds that file system using existing data. Unlike other utilities that attempt to repair problems in the existing directory, DiskWarrior creates a new directory. Given that a directory contains millions of data points, the process is simpler in theory than practice. Repairing a directory can make files and partitions reappear, improve performance, and even recoup disk space. If a disk is mechanically failing, DiskWarrior lets you repair your Mac's directory and back up its data before you replace the drive. Now that Apple has largely jettisoned disk drives, Alsoft ships the utility on a flash drive. (You can also create your own using a 2GB flash drive.) If your system is running OS 10.6 or earlier (preinstalled on Macs prior to 2011), you can boot directly off the drive by holding down the Option key.
Since Apple released its Recovery partition (with OS X 10.7), the process has become more complicated. You must boot into the Recovery partition (you hold down the R key), launch the Terminal (from the Utilities menu), and enter a command into the prompt (/Volumes/DW/go). It's important that to enter that command exactly: add a space or lose a slash and DiskWarrior won't launch. It took me longer than I care to admit to realize I had forgotten to include the forward slash before Volumes.
I encountered two additional, but easily resolvable, issues. The version of DiskWarrior included on my flash drive wasn't compatible with my operating system ( ). This hiccup gave me the opportunity to create my own bootable drive using the latest version of DiskWarrior Recovery Maker (v1.1), a three-minute process. When I booted into DiskWarrior, my drive registered as locked. I discovered that this was because I had enabled FileVault, which encrypts data.
Thankfully, DiskWarrior lets you disable the feature by clicking an unlock button and entering a FileVault password. Testing Results I tested DiskWarrior's three main functions.
S.M.A.R.T diagnostics, in the Hardware tab, reassured me that nothing was wrong with my three-year-old SSD. I used the Files tab to correct my permissions and scan my files and folders for issues. The test required about four minutes, after which DiskWarrior indicated that it had verified and repaired my permissions, checked the property list of 3,316 files, and checked the resource data of 2,847 files. Fortunately, no major problems were found. My directory, on the other hand, needed work.
Diskwarrior 4.3 1107 For Mac
The Directory tab includes a color-coded optimization index: green indicates that a directory is not fragmented; yellow suggests it's inefficient; and red indicates serious issues. My SSD was designated inefficient. I clicked the Rebuild button and watched the utility glide through ten steps.
After six minutes, DiskWarrior notified me that it had 'successfully built a new optimized directory.' I clicked Replace and hoped for the best. A moment later, I had a new directory and clean, green bill of health.
Replacing a directory isn't some academic issue. Since I ran DiskWarrior, applications launch quicker and—this surprised me—I gained about 20GB of hard drive space, not an insignificant sum on a 120GB disk. A senior Alsoft technician explained that as a directory becomes less efficient, it wastes more space. By replacing an inefficient directory with a more efficient one, DiskWarrior eliminates wasted space and makes it easier for the operating system to locate files and folders. A Great Utility DiskWarrior won't help you to recover the document or spreadsheet you accidentally deleted. For that, you should consider a data recovery utility, such as Prosoft Data Rescue 4 or Data Drill.
However, when it comes to repairing a Mac volume, a utility like Data Drill cannot compare to DiskWarrior, which, after more than two decades in the business, continues to offer the most effective tool for repairing and rebuilding Mac directories. As a result, Alsoft DiskWarrior is the PCMag Editors' Choice for data recovery utilities.
