The developers of DiskWarrior don’t offer a free trial version, so there’s no way for customers to test the software for free. Macs with the new M1 processor are not supported by the latest version of Disk Warrior.
On the official website, the developers have been promising a major new update with support for APFS for more than 2 years now, but nobody knows when it will arrive. Since then, not a single update has been released. That’s a huge downside considering that Apple has been using APFS as its default file system for some time now.ĭevelopment.
DiskWarrior supports only HFS and HFS+ drives. On startup, the application always minimizes all other open windows for some reason, which can be quite annoying when you have multiple other windows opened.įile system support. Select that, then proceed to Disk Utility and then Terminal as described above.Strange behavior. If the afflicted disk is your startup disk, you will need to do this in recovery mode: restart the computer, hold down option, and wait for the disk options to appear. I have had this fail several times before finally working so its important to keep trying. Substituting your disk identifier for the one already here. Then, open up Terminal, and type this: sudo /sbin/fsck_hfs -yprd /dev/disk5s2 Look for "Disk Identifier" right at the top. You can get it most easily by finding your disk in Disk Utility, selecting your partition (not the drive) and type cmd-i.
Try this, and don't give up till you've tried it at least three times.įirst, get the name of the partition of the failing volume. Still, Disk utility will certainly fail to fix it, and DiskWarrior will probably fail too.īut don't despair. Invalid Node Structure is not a hardware failure, it never was (you may still have a hardware failure, but the Invalid Node error is not indicative of this problem. Try this, in order to fix it (I posted this to the apple forums a couple years ago and I am still getting emails from people thanking me, so we know it works). I have repaired many disks with this error and they are all still running (and smart reporting as fine) years later. Hopefully that helps or at the very least gets you started. If it's not covered then I would get a quote from each shop.
If your Mac is under warranty (you can check with this tool) then the repair would likely be covered by both Apple and/or an AASP so long as it wasn't a result of accidental damage.
As I mentioned, the hard drive is the most likely culprit, iFixit has a guide that walks you through the process - MacBook Pro hard drive replacement. Depending on your comfort level working with computers you might attempt to repair your Mac yourself. If you're unable to do this then I would recommend checking with local AASPs (see two paragraphs down) to see about data recovery options. If your Mac does manage to boot again I would strongly encourage you to copy whatever important data you might have (pictures, documents, etc) to a thumb drive or external hard drive. Backup your data if you haven't already.The process of doing so is one of the most taxing procedures a hard drive is likely to go through in normal use, on a failing drive it can stress it to the point of complete failure.
Definitely don't try to install a new operating system.
