I am currently within windows 10 and have fossapup iso downloaded,I have a 1.9 terabyte usb drive plugged in but i have never installed puppy in this fashion.
For this big a drive and the fact that all the USB installer programs for Windows will do an install, but not partition and format correctly.
They will boot OK, but the ones that format the drive, usually do a ISO9660 format that will not allow making a save on the drive.
Take a much smaller USB stick and put Fossapup64 9.5 on it.
Boot the computer with it so you are running Fossapup64.
Use the programs in Fossapup64 to setup and do installs on this 1.9TB drive.
Here are some installer programs you can run in Windows:

I suggest using Unetbootin program.
It wants the USB stick formatted fat32 and does not do formatting.
So if new USB stick, it is already fat 32 format.
If not fat 32 format, make it that format, before using it.
Now with the computer booted using the Fossapup64 USB stick.
Partition and format the 1.9TB USB drive, whatever you want to, using Gparted program, running in Fossapup64.
Only requirement.
Make the 1st partition a small 300MB size, formatted fat 32, flagged boot, esp
This will be used for location of the boot loader files and be used as the boot partition.
The rest of the drive partition and format as you want to.
If Windows 10 is ever going to access it.
Make one partition formatted ntfs, so Windows 10 can see it and use it.
Use Frugalpup Installer to do the installs to the 1.9TB USB drive.
Frugalpup Installer program is already in Fossapup64.
It does frugal installs and also installs the boot loader to boot them.
From the main window of Frugalpup installer.
Puppy button does the installs.
After doing an install.
Boot button installs the boot loader to boot it.
Do the frugal installs on any partition, but not the first small one.
Place the boot loader on the 1st partition and only the boot loader.
If you want to install more frugal installed Puppies.
Just do the complete process over with Frugalpup Installer and the new Puppy version.
The new Puppy version will be a separate frugal install from any already on the drive.
When you do the boot loader install again.
It will find all the frugal installs on the drive and setup the boot menu, with entries for all it finds.
Note:
Here are some more detailed steps for using Frugalpup installer:

It talks about installing to a USB stick, but process is the same for any type drive.
Frugalpup Installer is now at version 38 and has some added features that the version 20 in Fossapup64 does not have.
You can download and install it from here:

May want to do this update before using it.
I used this procedure to have 15 different Puppy versions installed on a USB hard drive.
I can boot it and choose which one to boot.
Using it right now .
