It could be nightmarish if you have got the below message through Disk Utility while repairing an external hard drive formatted with APFS or HFS.
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 external hard disk errors. In most cases, the Disk Utility is vigorous enough to repair an external drive and even your start-up disk. But if the external hard drive is beyond the repair scope of the Disk Utility, then it could be possible that the directory structure of the drive is corrupt severely.
Don’t panic, the below 3 activities could be performed when Disk Utility fails to repair an external hard drive. Further, try Mac external hard drive recovery software as a last resort.
1) Backup External Hard Drive Data
Free up the space you want to give to bootcamp partition using the disk utility in macOS.remember how much space you freed up. Restart into bootcamp. In bootcamp, install minitool partition wizard (it is free). In bootcamp, open up disk management. Check how much unallocated space is on the hard drive. If it does not match the amount of space you freed up, then macOS created a new partition of.

HFSExplorer is a free tool for accessing Mac partitions from within Windows, but it’s read-only so it won’t help you here.

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.
Partition Tool For Mac
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 the 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 External Drive using Stellar Data Recovery Professional for Mac
Though helpful, FSCK isn’t the sure shot method to repair the corrupt external/internal hard drive. You might need the help of a professional external hard drive recovery software for Mac. Stellar Data Recovery Professional is a sophisticated application to scan and recover your APFS or HFS drive.
Step 1) Connect your external drive and launch Stellar Data Recovery Professional on your Mac. Customize your scan as shown below.
Step 2) Select your external hard drive and toggle on Deep Scan feature. The deep scan feature scans all the sectors of the external hard drive to bring back lost data. Otherwise, stick with Quick Scan to recover the file-structure. Press the Scan button.
Step 3) After the external hard drive scans complete, navigate through the Classic list, File or Deleted List to view and preview your files.
Step 4) If you have activated the Stellar Data Recovery Professional for Mac then you will be able to recover or save your files conveniently.

Reader Richard Lanier has a Windows issue—no, not that issue, but rather one involving size. He writes:
I’m running Windows 7 in a Boot Camp partition on my MacBook Pro. When I first configured Boot Camp I underestimated how much I’d use Windows and I’m now running out of space. How can I expand the size of the Boot Camp partition?
Let’s start by taking a look at a couple of tools that provide the means to a larger partition.

The easiest is Paragon’s $20 Camptune X (pictured above). What makes it so easy is that you tell Camptune the size you’d like your partition to be and, provided there’s enough free space on your Mac partition to give up some for Boot Camp, it takes care of the rest. I ran it last week on my MacBook Pro’s Boot Camp partition and after 20 minutes or so, my partition was increased from 30 to 40GB.
Easy though it may be, it’s always a good idea to have a backup of your Boot Camp partition before doing something like this. And for that backup the best tool around is Twocanoes’ $20 WinClone 3. Earlier versions of WinClone are not compatible with Apple’s latest operating system so while it may have been free once, it’s now something you must pungle up for.
That trades off bottoms-up planning for simplicity. It is primarily task oriented, and there is no effort required dimension to the tasks. The tops-down planning focus lends itself to more flexibility and quicker response to workload changes than traditional, details-focused project managers.
Those familiar with Winclone are aware that with its help you can create a larger Boot Camp partition without losing your original Windows data. The process involves creating an image of the partition for safe keeping, deleting the original Boot Camp partition with Disk Utility, creating a new, more expansive partition; and then moving the data from the imaged partition to the new one with WinClone. Twocanoes outlines the procedure in 25 steps.
Each has its advantages. Camptune requires far less work, but if your Windows data isn’t backed up in some other way, you face the small risk of losing data if something goes wrong. The Winclone way is more involved, but it’s safer.
Before leaving the subject, allow me to offer one other suggestion. Consider running Boot Camp under virtualization. Both Parallels Desktop for Mac and VMware Fusion allow you to import your Boot Camp partition into one of their virtual machines. Once you do this, you can resize their partitions. (Just to be clear, we’re not talking about the physical Boot Camp partition that you started with, but rather one you’ve imported into the virtualization application.)

If you have a Mac made in the last few years you’ll find running Windows under virtualization as pleasant an experience as Windows can provide—particularly if you devote more than one processor to it. It saves you from the bother of rebooting to use Windows and, of course, it’s completely cool to be able to copy files between your Mac and Windows environments.
