Drive external hard Mac has shown in the past but does not now show in disk utility. How can I get it back?

I'm going crazy trying to find an answer to this question! My external hard drive has shown in the past but not now shows in disk utility. My OS is X El Capitan.

I tried to turn off my computer then unplug my external hard drive waiting for 30 seconds back on my computer and plug my hard drive with no joy.

I hope someone can help.

Hi willy of San Jacinto.

I understand that your external hard drive is no longer seen by your computer. I know it's important to have a good backup location, and for that to work, I am so happy to provide assistance with this.

Read this article on troubleshooting USB devices:

OS X El Capitan: If a USB device does not work

If your computer is yet to see the hard drive after following these steps, it would be interesting to test this drive on another computer if available. If you continue to have problems, I suggest contacting the manufacturer of the hard disk on a hardware failure possible.

Thank you for using communities of Apple Support, cheers!
