Hi @jerrolg!

The first thing to check is the cable. Is it properly connected to your Mac? Have you tried connecting your external hard drive with a different cable? Or maybe the hard drive requires an external power supply? 

Next, try it on a Windows PC. There is a chance that the drive is formatted for PCs and not for Mac.

Another solution from apple is to use Disk Utility to access the drive and potentially fix the problem.

Here's a General File Recovery guide from the Apple Support Community. Hope this helps!
