WD Passport reformatted from Mac to PC (NTFS) capacity reduced from >100GB to 126MB

I just had to move files from a Mac to a PC. I copied all my files off of my WD passport, reformatted it for Mac & copied about 100 gb of photos from the Mac. Then I used HTFSExpress to pulled those photos off the Mac formatted drive onto my computer. Now I want to restore the drive to it's original state (Windows formatted & with the old contents). However, I've reformatted the drive as NTFS but the capacity (under properties) only says 126MB. Where'd the rest of the storage go?! I just pulled 104GB of photos off of this, why can't I put a similar amount of files back onto it?

I've tried reformatting it as all the options (FAT, FAT32, exFAT, NTFS) and I'm ruing Windows 10. I have no other computer to test this with.

Help please.
