Disk Warrior Free Download

[Cara Canellas]

My MacBook needs a good clean up and I used DiskWarrior in the past but it won't work on AFPS anymore. There are a few things that don't work fine, for example, I can't download my Apple books anymore.

I used DiskWarrior for checking and correcting or rebuilding the file directory. This would solve over 90% of my problems. This is what I want to do again but can't because it can't rebuild an AFPS directory. That's why I'm looking for an alternative,

APFS is proprietary to Apple and arrived with High Sierra in 2017. Since then there are a few vendors who have added support for APFS. But the built-in Disk Utility should be enough especially with modern SSD drives. Typically you would run the First Aid at the lowest level first and work your way up to the Container and then the Physical Disk.

Today's SSD drives are ridiculously stable and reliable. I have a tens of thousands of PCs and Macs at work and it is extremely rare for an SSD to fail. While HDD disks fail all the time. APFS was never really designed for HDD's and support was added later on after the initial release of APFS. Then they added Fusion Drive support after that.

That being said, most of the 3rd party products for APFS offer more data recovery features than disk maintenance features. Again, Disk Utility is recommended for any normal maintenance and repair. But if that fails and you have an HDD with bad sectors then something like this should help considerably:

I cannot stress enough the importance of backup in todays world of SSD and hardware level encryption on the newest Macs. If you have a backup, you don't need to repair or recover from disk failures.

There have been firmware updates from Apple where the MacBook Pro w/T2 screen and all the lights go out and it really looks like it's been turned off and people went and manually held the physical power button as a result. Thus interrupting a firmware update to BridgeOS running on the T2 chip and reset the T2 Secure Enclave meaning they wiped all the private keys out. Thus leaving you with an encrypted disk you could not recover even if you had the recovery key. The recovery key is a public key which has a private key pairing stored on the Secure Enclave within the T2 Security Chip co-processor SoC running BridgeOS. If the private key is gone the public key pairing will do you no good whatsoever. If you had no backup your data was gone with no chance of recovery. The only choice at that point was to perform an Internet Recovery to re-install macOS. This actually happened to dozens of users at my company. They received the macOS update and it ran and while it was updating BridgeOS (firmware update) they thought it powered off and held the power button till it booted and then they couldn't login to the Mac and all their data was lost. Apple has since put up text to indicate that it may appear off but it most certainly is not and to not interrupt the process. But it could still happen if they happen to power cycle the Mac at the worst possible moment during a firmware update on a T2 equipped Mac.

With the Apple Silicon Mac's you can't use Internet Recovery nor can you boot off external drives if the internal drive is gone and you will need a second Mac running Apple Configurator 2 and use a DFU Reset recovery method (much like an iPhone) to re-install macOS on the Apple Silicon Mac if you managed to brick it that badly. Most people will never brick an Apple Silicon Mac but people have done it by mistake. Especially engineers and those taking deep risks messing about trying unorthodox things or even orthodox things that used to work but no longer do with Apple Silicon Macs.

That is why backups are absolutely critical with the latest hardware from Apple. The combination of system board soldered RAM/CPU/SSD and the tightly coupled SoC to HBA RAM with fabric connectivity instead of a PCIe bus plus Secure Enclave hardware encryption makes it even more important. It is certainly possible to end up in a scenario where the Mac is bricked completely and if you don't have a second Mac you will need to take it to a repair shop to get macOS re-installed.

FWIW, even before any of the stuff you mentioned, trusting your digital life to a single device has always been an accident waiting to happen. Actually, two types of backups should be done as a backup itself can fail.

There is a lot of misinformation and confusion on this topic. Currently, no utility can rebuild the directory of APFS disks on Mac. That includes DiskWarrior (the best in the repair arsenal), TechTool Pro (second choice) and Drive Genius (third choice). Worst of all, macOS versions above 10.12 Sierra re-format disks as APFS, so users are left in the cold. Apple should not do that!!!

**Note: Optimization for APFS rotational drives is not yet possible with the current amount of APFS documentation provided by Apple, which currently provides insufficieant documentation for defragmenting a disk.

APFS formatting. No utility can fully support APFS at the moment, both because APFS is itself a work-in-progress, and Apple has yet to release documentation for it for developers. What is needed is documentation at least as detailed as the one for the HFS+ filesystem.

Using DiskWarrior 5.2 while started (booted) from High Sierra or Mojave. What's in the works. The next major release of DiskWarrior will include the ability to rebuild APFS disks. Apple has recently released the APFS format documentation. Our developers are now using that documentation to update DiskWarrior to be able to safely rebuild APFS disks.

That is FALSE. They CANNOT release a new version of DiskWarrior to rebuild directory of APFS until Apple releases the full documentation. Clearly, they do not want to reveal the plain truth, since their living depends on that! Alsoft should not do it!!! Customers deserve the truth!

SO, THE CONCLUSION IS THAT SOME DEVELOPERS ARE NOT TELLING THE PLAIN TRUTH, BUT AT LEAST ONE IS. IT IS IMPORTANT TO SEND FEEDBACK TO APPLE SO THAT THEY RELEASE DOCUMENTATION ABOUT HOW TO WRITE TO APFS DISKS AS THEY HAVE DONE ABOUT HOW TO READ THEM. THEN AND ONLY THEN THE REPAIR UTILITIES WILL BE RELEASED TO REBUILD THE DIRECTORY OF APFS DISKS:

Disk Warrior is much better and efficient repairing damaged disks than Disk Utility, because only the former rebuilds from scratch the directory of HFS+ disks. I am still waiting for DiskWarrior 6 to do it with APFS disks.

In relation to Stellar Data Recovery Professional, it does not repair disks; it recovers files from them. Thus, they are completely different applications. It is good to have both and use them depending on the issue to address (repair disks or recover files). The best is to repair disks, but if that is not possible, the second can help to recover files to other disk (the damaged disk will continue being damaged with such second approach).

Thank you for the detailed response. I appreciate the info and your expertise. Hopefully, the day will come (soon) that Apple releases complete documentation of the APFS file system so developers and the rest of us can get on with our lives. : )

Once you get the drive fixed make a backup and then either run the defragment tool or reformat the drive and install a fresh OS onto it then recover your data from the backup (TimeMachine) being the better one.

I've tested the drive itself in DRIVEDX and it has 100% health. it's a 1 month old seagate firecuda 1 TB SSHD. It's running the most up to date version of Mojave. I think her data is corrupt, because i've moved the drive to multiple MacBooks and get the same error.

Use TimeMachine to create a backup and then restore to a fresh drive to double check to see if the corruption is resolved. I'f possible format the test drive HFS+ so you can then use the better tools. Once you feel confident the spare drive is good, reformat the Seagate and re-install macOS as needed. I would strongly recommend you use Migration Assistant.

Not surprised at the criminal monopoly, conspiracy theorist have also gone as far as alleging Jobs was assassinated by the government who has been in the backseat of Apple since the hiring of ex Cyber Security from NSA which kind of does match the whistle blowers info out there about the domestic spying abuses against citizens including the current president for personal gain or investment interests carried out by agencies with zero over sight from DOJ or the office of the inspectors General,

But regardless if any of this is true or really spread miss information to smear america its just shows the lack of trust people have with Apple and all these sketchy data recovery apps that require you to be online to use them.

I use a few of these apps and I don't need be online to use them. This gets into if you are buying a standalone app or a cloud based app. As an example MS Office can be bought as either as installed app on your drive (no network access at all) or as a service via cloud.

Of course companies will go the direction most profitable, but im just saying that T$m Cr00k will and has openly ventured into illegal areas that have not yet been addressed by our US or international courts ,

He is a pro at it, for example, while with Jobs he was the one flying to China visiting child slave factories and arranging shipments of 3,4 quarter batches of devices to contain toxic cheap parts assembled by child slave factories., more cuts more profits and its true, Apple has been fined over and over and they dont mind paying the fines as Mr$ Crook has learned that paying the fines is also more profitable then recalls, paying class action law suites off etc cause Apple makes $350 million an hour from all this itself,

BTW did you know that Catalina has a backdoor as wide as Opra's fat tush just begging for a justification to get your device bricked remotely, some times for as little reasons as some random p0rn advert appearing on a webpage while your browsing netflix.
