“Then I notice the sd card was using the file system NTFS”
Which makes me wonder anyway as I wasn´t aware that NTFS was shipped generally with media other than if being used by Windows.
I have never pre-checked any sd card or HD for which fs is on it. Usually formating and/or partitioning is my very first step.
Again this shows how vital it is to do so, as using media fresh out the pack without any further action may rise unexpected troubles some time later.
