Note: Make sure you’re burning a bootable ISO and not just the data.

We’ll use Mint for this, because it’s the most likely to have the relevant proprietary graphics card and wireless drivers for your mac. We can also recover the data on the disk using a Linux liveCD. Step 3b: Data recovery without target mode When done, eject the target machine’s drive and restart it.From the host machine, you should now have access to the target machine’s hard drive.Turn on the target machine, holding down the T key as it boots up.

#OS X DISK REPAIR INVALID NODE STRUCTURE MAC#

Connect it to your broken mac (the target machine), which should be powered off. You’ll need another mac with a firewire port (the host machine).

If you don’t have access to another mac or your computer doesn’t have a firewire port, skip to step 3b. The easiest way of doing this is with Apple’s firewire target mode. The best we can do now is salvage your data, replace the broken drive and restore the data. If fsck_hfs failed to repair your disk then we can safely assume it’s beyond repair. If you’re confident that your problem is not with your hardware, however, this would probably be a good course of action.įor detailed instructions, check Diskwarrior’s documentation. In other words, you’ll soon need to go through this process again, and again, and so on. Thing is, the problem is almost certainly caused by a hardware fault, so it’s likely that the best DiskWarrior can do is treat the symptoms of the problem but not the cause. It’s pricey but there are lots of reports of it solving this particular error. Optional: DiskWarriorĭiskWarrior is a commercial program that repairs problems with Mac hard drives. Otherwise, it will have fixed the problem with your file system’s catalog, and you can go back into Disk Utility and click repair, and it will work. If it tells you that the system cannot be repaired, go on to the next step.

Enter ‘fsck_hfs -frpy /dev/diskNsN’, replacing in the correct numbers.

You need to identify OS X and take note of its name (in the format ‘diskNsN’).

Enter ‘diskutil list’ to get a list of all the drives on your machine.

Go to the utilities menu and choose Terminal.

Select the partition that OS X is on and click Repair Disk.Īt this point it’ll either fix the problem and you can go on as normal, or it’ll throw an error and you should move on to step 2.

When the welcome screen appears, go to the utilities menu and choose Disk Utility. I’ve occasionally experienced problems with this process, so if this doesn’t work hold the Option key and you’ll get a menu to choose which disk to boot from. When the spinning disk appears you can let go.

Restart your computer, holding the C key as it turns on to tell it to boot from the installation disk.

Insert the OS X installation disk that came with your computer.

Symptoms of this problem include an abnormally long boot time with frequent kernel panics, and then when OS X does manage to load it will be too slow to use.

Damage likely caused by a failing hard drive. An Invalid Node Structure indicates damage to this data structure. HFS+ uses a catalog system to keep track of files and directories. Apple use a file system called HFS+ in OS X. Of course, there are a couple of things we can try before we give up. It’s unfortunate that SSD’s don’t yet come standard in every new computer, because the only thing reliable about today’s drives is that they will reliably fail. I’m going to start this post with something you probably don’t want to hear: if you’ve googled this article then there’s a good chance your drive is already a lost cause.
