Files on my SD card disappear when being copied

[Windows Central Question]

Good day! I have an SD card 512GB class 10. I am using my laptop reader and I have windows 8 64 bit installed. The SD card format is changed from default( ExFat) to NTFS.

When I copy a file to the SD card and the file or directory is too large, I think over 10GB, it disappears! The system shows that the space is taken, I have used mini tool partition wizard to verify the sectors and they are all OK. I formated 50 times in different formats and I get the same problem! Does anyone have ideas!

OS: Windows 8 64 bit, licensed, original
Laptop: Asus X55VD
SD card: Unbranded/ Generic class 10 512GB

Is it possible that this is a problem from windows?

so does the sd card still show that the space has been used up?
Or you can't copy that file to it?
