Disk Warrior versus Data Recovery

Disk warrior has long been a favourite utility used by mac support companies and enthusiasts to analyse and repair Macintosh disks. It is favoured mainly for it’s simplicity and many features including data recovery.

As a data recovery company we have received many mac hard drives from clients who had previously used Disk Warrior to attempt to gain access to their data. In some cases the particular hard drive being examined was too severely damaged for Disk Warrior to be of any use. In other cases Disk Warrior was used but the data left afterwards was corrupt and not accessible.

The problem is not so much the utility itself, but the lack of a users understanding of how powerful this utility is. This is a quote used on Alsoft’s website that can be misleading.

“ Simply click the rebuild button and Disk Warrior goes to work ”

In any data loss situation writing to the hard drive that has your lost data is something that should never happen, as it is this writing process that can do more damage than good. If you allow DiskWarrior to write a repaired structure to your disk, you lose any chance of getting back data what was missed out. If the rebuilt data is damaged, the disk will be in a worse state than the original failure.

We recommend that you read the documentation that comes with the utility carefully and fully understand its capabilities.
