How to fix invalid node structure error? Using DiskWarrior?

Posted by Juno to Mac Data Recovery on January 30th, 2018

I was using my external hard drive yesterday, and everything was fine. I plug it in today but it does not mount. In Disk Utility, it does see the drive and the single partition, which is not mounted. Trying to repair the drive with Disk Utility, I get the error message that there is an Invalid Node Structure and it cannot be repaired. Can I use DiskWarrior to fix this error? Or is there any other tool can help?

'Invalid node structure' error usually indicates that the directory structure of a storage device has been corrupted. This is quite tough an error and no user want to experience. No matter what, when encountering invalid node structure error, the first and most important thing we should do is to find method to fix it.

Some users may want to use DiskWarrior to fix invalid node structure error. But actually, DiskWarrior is not recommended at all.

Why we shouldn't use DiskWarrior to fix invalid node structure error

Here are several shortcomings of DiskWarrior:

1. Sometimes, it can't fix invalid node structure error: Although DiskWarrior claims to be an advanced repair & data recovery tool, there are times that it fails to fix invalid node structure error or recover data from drives.

2. DiskWarrior doesn't support APFS data recovery: On macOS High Sierra 10.13, the default file system is APFS. If our drive has been formatted to be APFS, it is impossible to recover data from our APFS drive.

3. Relatively high price: It charges US$119.95 and that is relatively higher that other similar software.

4. Paid upgrade: It should be noted that DiskWarrior doesn't offer free upgrade and we have to pay US$59.95 for every upgrade. As we usually use this software for a long time, the upgrade costs should also be taken into consideration.

Due to the reasons above, we should avoid using DiskWarrior to fix invalid node structure error. Here is a reliable method to help fix this error.
