Just by doing the above USB cable transfer procedure( no USB actual eBook transfers) will always force the Kobo to do a full scan of all memory(internal and external) and then update the Kobo ereader eBook catalog listing file .
Yes, you are correct, connecting and disconnecting from USB will trigger scanning for changes in the books. And if you do what you said, shut down, take the internal card out, put books on it, put the card back in and restart the device, you will need to do this have the books imported.

But, that is not what @Airlane1979 is doing. They have a card in the external slot. In the Touch, these are not loaded when the device is powered on. It is a bug that has been around for a long time. And, it doesn't help to connect to the PC and eject. That doesn't force recognition of the SD card. Ejecting and inserting the card does.

you have to manually boot up the Kobo only if whilst the Kobo is doing scan/updating is if the power option for auto power off is set to a timeout value which is shorter in time than the time needed to fully complete the update procedure(this can happen ,if like me, you have a very very large number of eBooks on your Kobo or are using a slow read access time SD card) leading to the Kobo powering off but still displaying the black USB transfer screen(no displayed indication that the Kobo has actually powered off/down) .
Sorry, you have the automatic power time lower than the amount of time it will take to processes the books? Why? If you know it is going to happen, why don't you extend that time? Or turn it off and leave the device connected while the books are imported. Even just using sleep is better as you can wake it and it will continue doing the import.

I have a Kobo Clara and I regularly remove the internal SD card and insert the internal SD card(A2 version 128 gigabyte) in my PC and transfer a batch of my newly purchased books to the SD cards fat32 partition inside a directory named 'Books'.
then reinsert SD card back in Kobo and cold boot up Kobo Clara.
then I follow the above USB cable transfer procedure( no USB actual eBook transfers) to update the Kobo ereader eBook catalog listing file.this is much much faster than actual transferring all the books by USB serial cable.
Exactly how many books are you copying over each time? I can see doing this once to populate the device the first time. But, after that, you would have to be adding 10's of thousand books each time to be worth the hassle.

if the external SD card has any Fat32 File system errors or if it was removed from windows pc without first selecting the file-managers eject/unmount menu option then it will not be detected as a ExtSD card on boot up.
eject ExtSD card and insert in PC.
inside windows pc file manager do a properties/disk error scan to correct any fat32 file system errors.
make sure to use the file-managers eject/unmount menu option before removing ExtSD card from Windows PC .
reinsert SD into Kobo and do cold boot-up.
the SD card should now be recognised after booting.
the old Touch has a slow processor/internal sdcard(in comparison to recent Kobo models) so be very very patient waiting for the extSD card to complete the scan after cold boot-up.
As I stated, there are multiple issues with the external SD card in the Touch. Ensuring that the card is not dirty is easy to check and fix if necessary. At this point, it is more likely that the 32GB card being used by @Airlane1979 is one that the Touch cannot use for some reason. This was discussed when the Touch was the main Kobo device and the SD cards were starting to get larger. There are no issues with 2GB or 4GB cards. But, larger cards could cause problems. Some could be fixed by reformatting them, but, other cards just didn't work. My memory suggests not going past a 16GB card in the Touch. And even then, I don't think they all worked.
