8 Tips to Fix Can’t Delete Files from USB/HDD on Mac

Tip 1. Restart Your Mac, Reconnect the Drive to Mac

If you are unable to delete files or folders from a USB flash drive or external hard drive on your Mac, you can restart your Mac and try again. You should also make sure that the drive is well connected to your Mac computer. You can disconnect the drive and reconnect it to delete files again.

Tip 2. Make Sure the File Is Not in Use

If you meet the “File in use” error when trying to delete a file, the file may be opened or used by another program. Make sure to close the file. Close all open applications on your Mac and try to delete the file again. If you don’t know which program is using the file, restart your Mac and it should terminate all programs.

Tip 3. Check for File Permission

If you can’t delete files from USB on Mac, you can check if the file is read-only.

  1. Right-click the file and select Get Info.
  2. Expand the “Sharing & Permissions” section.
  3. Check if you have the permission to delete the file. Change the privilege to “Read & Write”.

Tip 4. Check If the Disk is Write-Protected

Tip 5. Fix Can’t Delete Files from an NTFS Drive on Mac

You can check the format of the drive in Disk Utility to see if it is in NTFS format. Mac has limited support for NTFS-formatted drives. It only lets you read files on the drive but not write, edit, or delete files on the NTFS drive.

To enable Mac to write, edit, or delete files on the NTFS drive, you need to use a professional NTFS for Mac software.

BuhoNTFS, a top free Mac NTFS tool, helps you mount NTFS drives read and write on your Mac with one click.
