Did you follow these steps EXACTLY. Note is says FAT32 and NOT NTFS. If you are still on NTFS on your external USB drive you will have to reformat it to FAT32. That should fix the issues ... I had similar issues with an external USB on a PS3. Tried for days (literally) to get it to work. Converted the drive from NTFS to FAT32 and it worked straight away. Not sure why NTFS screws it up but it does

First Update the RetroPie Setup Script
Re-Enable the USB ROM Transfer Service
Format your USB drive to FAT32 per directions above
Create a folder called retropie-mount on the USB drive
Plug into Raspberry Pi
It will proceed to automatically copy the RetroPie folder AND all of its contents (you may need to reboot to start the copying)

Note, that you MUST disable the USB ROM Transfer Service AFTER everything has been completed and copied over, that can confuse things as well

If your USB drive is NOT FAT32, have a look at these links to explain how to convert from NTFS to FAT32. It can take quite some time depending how full your USB drive is. Be patient if you do convert it will work eventually and DO NOT be tempted to stop it. Your USB drive must be plugged into your PC though ....

NTFS is the preferred format these days as filesizes over 4GB are not supported in FAT32 and will cause a copy error if you try to, but as everything on RetroPie is well under 4GB filesizes that isn't an issue here. Even if you try MAME CHD games they are all under 4GB. Not that the PI3 will run all of them, but that option is there if you wish to try once you've got it running

If you are not 100% sure what filesystem your USB drive is, in the My Computer folder, simply left-click your USB drive once and it should tell you what it is either NTFS or FAT32. If not, right-click your USB drive and choose'properties' at the bottom of the drop-down menu it will then show another windows with the filesystem clearly shown as NTFS or FAT32. Pretty much every USB hard drive I've bought is now already NTFS format

If nothing works, you might have to rebuild an image from scratch. I've done it this way in the past and installed a minimal OS image from the NOOBS option, and rebuild RetroPie manually. More work, but guaranteed to work if the RetroPie image is causing headaches

Use the NOOBS_LITE download which is the bare minimum and you then choose what OS to install. But you NEED an internet connection. Preferably an ethernet one as its much faster than the PI's wireless connection

Then follow these steps EXACTLY. If you have already installed the OS using the above method, then just skip to the INSTALL RETROPIE step and work from that. It does work this way as I've installed it this way when I've also had issues with the RetroPie pre-built images in the past

"Custom" hard drives always cause problems for future updates, as its basically just shovelware. They install functioning software package and just load everything onto the drive and you are left with basically with zero after sales support and hundreds of games that are not suitable for that set-up

NTFS is supported by the retropie-mount routine. It's working 100% fine here with a 3TB NTFS file system on a external portable hard drive.

@clyde not trying to make things more difficult. Just giving another option in-case he can’t get the official method to work.

And I mistook you for the TO, that's where my last paragraph about helpful details came from. :*)
