DiskWarrior Files & Folders Check

In a recent article, I bragged about the super powers of the DiskWarrior repair and recovery tool from Alsoft. One of the features I mentioned was it’s ability to check Files and Folders for corruption. I thought I would focus on that feature a bit. To be quite honest, I have not used it too much, but it does seem like a good practice to keep my Mac as clean and trouble-free as possible.

DiskWarrior Files & Folders Check

I performed a check of the Files and Folders on my iMac backup drive. To check my main drive Diskwarrior says it needs to be booted from some external media. I have a Tech Drive with Diskwarrior on it, but I did not wish to take the time to boot into the Tech Drive, so I ran the check on my external iMac Backup drive.

Checking Files and Folders on a drive is a three step process:

  1.  Select the “Files” Tab in the DiskWarrior window toolbar.
  2. Click on the drop down and select the drive you wish to check.
  3. Click on the “Start” button and you are off and running.

DiskWarrior begins its check of the Files and Folders on that media:

My backup is large so this check took quite a while, maybe 20-30 minutes or so. Once it had  finished the App presented the results:

As you can see, there were two files that DiskWarrior flagged as “damaged.” As far as I can tell there is no mechanism within DiskWarrior to go straight to the files in question. I navigated to each file on my iMac Backup and deleted it. By the way, since these files are damaged and they are from the original source, it was only logical (yes, I have Vulcan heritage) to assume the original file on my Mac was damaged as well. So, I deleted the same files on my Mac so as not to back them up again.


Admittedly, I have not used this Files and Folders check in DiskWarrior too much formerly, but I will be using it periodically in the future. It is another weapon in our clean running Mac arsenal.
