My external USB drive, formatted as NTFS, is no longer being recognized in High Sierra.

As soon as I plug it in I get the following error message:

I tried running First Aid in Disk Utility but it is greyed out.

I then tried to verify the disk in Terminal and this is what it spit out:

When I type in diskutil repairvolume /Volumes/SSD/ it spits out the same error and then un-mounts the drive.

Is my drive corrupted beyond repair? Any help would be much appreciated.

Thanks.

I fixed it by performing a chkdsk /f in Windows.

  • Welcome to Ask Different! :) And thanks for coming back to share how you resolved it. Can I ask you to edit your answer to provide some more details? In particular explaining how you perform a chkdsk /f in Windows will probably help a lot of users who wouldn't know where to begin. – Monomeeth Feb 13 '18 at 5:39
  • It should also be noted that anyone can download a free Windows VM from Microsoft (via the modern.ie project) and then run it from a Mac or Linux computer via VirtualBox. – Andrea Lazzarotto Feb 13 '18 at 13:26
