"Invalid Node Structure" "The Volume Machintosh HD Could Not Be Verified Completely" is one error every Apple OS user must fear, the error is a sign of corrupt storage disk directory structure and the Mac OS X built-in Disk Utility fails to fix the problem. Most of the time a user would get stuck at the Apple Logo with the spinner, even if you are lucky to boot into the operating-system you will find missing applications and issues with your dashboard depending on which part of the directory catalog got corrupted.

Luckily, we do have quite a few tricks and tools up our sleeves to get this handled properly fixing the system making sure maximum possible data recovery. In this post, I will be sharing three possible solutions to get this issue resolved.
