There are a number of Mac data recovery software that are perfect alternatives of DiskWarrior tool. They can repair a corrupted or damaged Apple Mac hard drive and also recovers deleted/lost files from the Mac drive or volume without any single digit change. However, after using all of them, I have found '''''TechSoftwareLogic Mac Data Recovery Software Application Tool''''' just few months from an Apple thread and found it quite useful for data recovery purpose. This is the best DiskWarrior alternative and provides a number of features like BootCamp partition recovery, deleted partition recovery, lost files recovery etc.
