Basically, I could not get external drives (USB and Thunderbolt) to automatically mount to Finder/Desktop on startup. I could see the drives in Disk Utility and do an unmount/mount action to get the drives to be visible. I have checked all of the formatting.

I have been trying to fix the same issue for three days and may have finally found a solution. I have a G-Drive on Thunderbolt and a seagate USB 4 TB as well as a WD My Book, all of which would not show in Finder but would show in Disk Utility. On one of the apple community areas I fund this terminal command:

sudo defaults write /Library/Preferences/SystemConfiguration/autodiskmount AutomountDisksWithoutUserLogin -bool YES

This has worked for me. I am NOT an IT expert but this terminal command seems to change a default SysConfig to allow drives to mount without the user login (doh) ..

As I said, I am not an expert but this has worked for me (and yes, I did try firmware, 3rd Party Utils, etc) ..

Hope it helps - perhaps someone with knowledge and experience can confirm the above for others to try?
