Mac Can’t Repair HFS Hard Drive. How to Resolve?

It could be nightmarish if you have got the below message through Disk Utility while repairing HFS formatted internal or external hard drive.

Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk and restore your backed-up files.

The above message doesn’t show up in normal circumstances of disk errors. In most cases, the disk utility is vigorous enough to verify & repair your Apple hard drive. But if the HFS hard drive is beyond the repair scope of disk utility, then it means the directory structure of the drive is severely corrupt.

Following 3 activities could be performed when Disk Utility fails to repair or recover Mac hard drive.

1) Backup Data

You can try copy and paste all files from the corrupt external or internal hard drive to another destination. But doing this may also result in copying errors to another location. Moreover, the corruption may not allow you to copy & paste all the files from the disk.

2) Fix Mac hard drive using FSCK

You might have luck with FSCK command line.

To run fsck command you have to restart Mac and log in as ADMIN. Launch Terminal, enter df -h1 and press Return. Use of df-h1 will let you know the path of the internal disk drive.

Use below line

sudo fsck_hfs -r -d /dev/disk1s1

The command (-r) in above code will recreate Catalog B – Tree. It will help you fix Invalid B-tree node problem occurred on the disk drive. It will further resolve errors like –

  • Invalid count
  • Invalid key length
  • Invalid volume file count
  • Invalid volume directory count
  • Invalid volume free block count, and likewise.

3) Recover Mac disk using Stellar Data Recovery Professional
