How to Repair an External Hard Drive on Mac

If you're having trouble accessing your external hard drive on your Mac, there are several steps you can take to try and repair it. One option is to mount the EFI Partition on Windows if you don't have access to a Macintosh or Hackintosh computer.

To do this, follow these steps:

1. Connect your external hard drive to your Windows computer.

2. Open Disk Management (Press the Windows key + R, type 'diskmgmt.msc', and press Enter).

3. In the Disk Management window, find the external hard drive and right-click on it.

4. Select 'Load File System from Device' and then click 'Autodetect' to load the connected hard drive.

Another option is to use the built-in Disk Utility app on your Mac to repair your external hard drive. To do this:

1. Connect your external hard drive to your Mac.

2. Open Disk Utility, which can be found in the Utilities folder of your Applications folder.

3. Select the external hard drive from the list of available disks and click the 'Unmount' button.

4. Then, click on 'Mount' and select 'Force' as the mount option.

If you're still having trouble accessing your external hard drive, you may need to use a third-party tool such as APFS for Linux by Paragon Software to connect to it from Windows or macOS.

In some cases, you may need to create a mount point for the volume where the system's root volume will be mounted. To do this:

1. Open Terminal on your Mac.

2. Type 'sudo mkdir /mnt' and press Enter to create a new directory called 'mnt'.

3. Then, type 'sudo mount -t Apple_HFS /dev/disk3 /mnt' (replace '/dev/disk3' with the path to your external hard drive).

By following these steps, you should be able to repair your external hard drive and access its contents again.
