Yes, that is the likely explanation. I do not know the fix, but I know of an easy and effective workaround that is also a good tool for many similar IT problems: keep a live Linux USB stick handy. Boot to that, no need to install anything, it will support pretty much everything and gparted is the king of reformatting. Linux Mint is highly recommended to those who doesn't want computers to be complicated.
