Is it possible to boot DiskWarrior from USB?.Alsoft DiskWarrior Data Recovery Process.It’s unable to help when the data loss is due to human error, such as deleting the wrong file or formatting the wrong drive. It can help when the data loss is due to errors in your Mac’s directory structure. It can also help you rescue a failing drive by creating a disk image.īecause it works differently from most other data recovery applications you should see it as a complementary tool rather than a competitor.ĭiskWarrior costs $119.95 (one-time purchase) and can be purchased directly from Alsoft, the developers. That includes both a software download and a bootable flash drive. ![]() There is no trial version, so your first step will be making a purchase. The website stresses that all sales are final, and even requires you to press a button to confirm that you understand and agree with that. That means that most users should definitely not purchase the current Version 5 Edition of the software. Wait until Version 6 and confirm that it works with the APFS file system. If you know that you have an older Mac with an older file system and intend to keep it that way long-term, DiskWarrior 5 is a worthwhile tool. It will keep it running faster and eliminate a range of file-related problems from happening. Reads damaged directories to locate and rebuild salvageable files and folders.Eliminates directory errors and optimizes directory performance.SMART monitoring for early warning of failing hard drivesĭiskWarrior takes a different approach to other data recovery applications.That means that it’s able to fix problems other tools can’t. It also offers preventative maintenance that solves problems before they happen. To facilitate that, the company recommends you run the software once or twice a month. macOS High Sierra (10.13) but doesn’t support internal SSDs.macOS Big Sur (11.0) but only for external disks with the macOS Extended HFS+ File System Format.That last point is crucial to understand: Apple’s new APFS file system is not currently supported. That makes it useless for many users, including myself. All internal drives on current Macs are formatted APFS. The developers have provided a document that explains how to tell if your Mac uses APFS. ĭiskWarrior also does not support FAT-formatted drives, which many flash drives and memory cards use so they can be accessed by both Macs and PCs. Users have generally been satisfied with the software but user ratings have dropped since the software became incompatible with Macs using APFS. Ratings are currently average to good depending on which site you check. 179 users gave it 4.1 stars on CNET and the vast majority of reviews are 5 stars.460 users on MacUpdate gave it a lower 3.4 stars.154 users on Amazon award it a slightly higher rating of 3.8 stars, and again, the majority of reviews are 5 stars.Will DiskWarrior effectively recover your lost data? Let’s start with the obvious-if you have a modern Mac your internal drive will be formatted with the APFS file system, and it won’t be very effective at all. You will be able to repair external Time Machine hard drives, and any drives formatted with an older Mac file system such as HFS+.īefore APFS, DiskWarrior had a very good reputation because of its ability to solve problems no other app could. One user review on MacUpdate puts it well:įor years DW has been the ONLY app that could fix broken Mac OS directories – that is until APFS… Since DW can’t talk to APFS volume directories it wouldn’t surprise me if their sales have gone to near zero. Some users gave negative reviews because they were because the software was unable to rebuild an SSD. But that’s a problem with SSDs, not DiskWarrior. The TRIM technology that increases their efficiency also makes data recovery difficult. Other users reported that the software was successful at repairing dead SSDs. Who should use DiskWarrior? Users running an older Mac with a spinning hard drive formatted with an older file system may find that DiskWarrior keeps it running fast and problem-free. If that’s you, it’s a purchase worth considering. The Alsoft Technical Support Page lists FAQs, new features, and compatibility news. There are links to startup instructions, video guides, requests to resend the software, how to identify APFS disks, product registration, and more. Support can be contacted via an online form.
