Is it advisable to rebuild directory of disks with DiskWarrior on a regular-basis, as routine maintenance?

Even if disks are filled with issues when checked with DiskWarrior? I have saved many Mac disks with DiskWarrior that were otherwise broken. Sometimes Disk Utility broke even more such disks and DiskWarrior saved them. This is a solid experience with thousands of Macs for many years at our University.

Believe or not, what I said is true. Google for it and you will find many examples. DiskWarrior is an awesome repair utility that can save otherwise broken disks. In my case, I have also experienced it myself for many years as said.

I am asking because I want to know what other's experience is. Since it was different to mine, I have reported mine for the record. And searching Google supports what I said. You say that DiskWarrior is worthless. Really amazing.

Sure. The problem and the reason for my question is: what happens when you do not know if the disk structure is damaged? You will not know for sure until you run DiskWarrior. So, yes, DiskWarrior makes only sense if such disk structure is damaged, but you must run it to know.

So, in such context, I understand that running DiskWarrior is not only a must when disk structure is damaged, but also for routine maintenance to check if disk structure is damaged. Because if it is indeed damaged and you do not know and you do nothing to fix it, you may eventually lose all data. That is my experience over years, as said, and wanted to know what other users's experience is.

Here are just two reviews from respected experts among many others after searching Google for

Essential Mac Maintenance: Rev up your routines

A more-thorough option is to use Alsoft’s $100 DiskWarrior 4.1( ), which has long been the gold standard for directory fixing.

Alsoft DiskWarrior 5 (for Mac)

By William Fenton

Alsoft DiskWarrior 5 is the data recovery software that Apple forgot to include. In fact, that isn't entirely true: Apple once bundled the third-party utility with AppleCare. Today, the utility is no less useful for a swivel-neck iMac or a MacBook with a solid-state drive (SSD). In fact, Alsoft DiskWarrior 5 is one of the best utilities you can buy for your Mac.

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 Prosoft Data Rescue 4 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.

Concerning Command-line versus GUI:

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.

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 5 is the PCMag Editors' Choice for data recovery utilities.

I do not know Terminal commands, and I know they can be dangerous if you type something wrong. It is much easier to use a Graphical User Interface (GUI). This is Mac, after all.
