You can follow to resolve the same issue on your own now. Here we'll take the unmounted external hard drive as an example to show you how to force the unmounted external hard drive show up on your Mac desktop without losing any data. Have you ever met this problem that you tried to open an external hard drive on your Mac computer but the disk displayed as unmounted? If yes, you are in the right place. If Mac is not compatible with the drive format, use Disk Utility to erase it to Mac OS Extended. If you lost drive data, run EaseUS Data Recovery Wizard for Mac to bring it back. Open Disk Utility > Select the unmounted external hard drive > Select "Mount". Check external hard drive cable, the USB port on Mac, and its state in Disk Utility.
