Hi, I have this external hard drive -'Seagate Expansion Desk Media' that is powering up, but not being recognized in Disk Utility. I have tried to use first aid, without any luck. Any suggestions? Thanks

Therefore, how to fix the external hard drive not showing up in Disk Utility? Here are some solutions for you to fix it.

  • Manually show external hard drive in Disk Utility
  • Reboot your Mac computer to recognize the external drive again
  • Check the external hard drive in System Information
  • Reset the USB ports of your Mac
  • Check for hardware and software updates
  • Run a virus cleaner software
