A new 64GB Micro SD card came with 59.4GB of available storage, knowing how storage drives work that's to be expected.

My question is in the available storage there was 400 and something KB of used storage (that stuck around even after formatting) which I can't figure out what it is since no files show up when exploring the SD card even after enabling the computer hidden and system files setting.

Well, the file system itself along with its Volume Table of Contents takes up some room even when there's nothing else.    400KB is very little space.  This is strictly a guess as to exactly what this might be, but no empty drive that's been formatted is truly empty.

My question was not about the 59.4GB. My question was about the roughly 400KB of files/data that the card supposedly has but that isn't visible. Is it a normal thing for new SD cards to supposedly have a bit of files/data on them even though the drive is empty when clicked on in Windows Explorer?

If it's not visible...then it's not "file data" but likely the typical amount of space used when any partition is created on any drive..400kb of space is not an unreasonable amount of space to expect for such.  There is no reason to expect such to be visible.

But a 16GB USB that I once got didn't have any "partition data" on it at all. The 14.9GB of available storage was totally empty as opposed to this one that had some KB of data in the available storage.
