I just installed macOS 10.14 Mojave system on my macbook pro retina display. The system is gorgeous and everything works perfect, until today, I found a problem:
when I plug in my external hard drive (Mac format) to my laptop, the system just cannot recognize it and the external hard drive just doesn't show on "Lacations" in my Finder.
Did anyone meet the same problem?
MacBook Pro (Retina, 13-inch,Early 2015), macOS Mojave (10.14)
Try another USB cable is the easy first try.
I have one drive (single-cable USB 3) that simply WILL NOT mount on a friend's iMac but will on mine reliably. When I swapped cables for a thicker one, that's the only difference I saw, it mounted as expected on both Macs.
You could also try resetting the NVRAM and SMC and also boot into Safe Mode then reboot right after not in Safe Mode.
Safe Mode = Boot with Shift held down until you see "Safe Mode" on screen. This purges lots of cache files. Then reboot again normally.

Sorta often the Mac needs to clear its caches and things after an OS update.
Thanks, but this didn't work for me. My drive dismounted 5 minutes after I remounted it....like it always does
same issue here
Starting in safe mode, then restarting worked for me! I've tried so many things over the past 4 hours. THANKS!!!

This also worked for me! My Drive was formatted in Mac OS Extended (Journal)
Thanks W. Raider. I had this problem and solved it by rebooting into Safe Mode, followed by rebooting again normally.
The Mojave cannot recognize external hard drive.
