SD Card file system crash when moving files?

OS: Windows 10 64 Pro

Hi,

wasn't sure where to post that topic, so I went here 'cause I don't really know the error causing it (yet).

Problem: Whenever I move (RAW+jpeg) files from my (128 GB) SD card, the file system crashes at some point. Sometimes when all files are moved, sometimes after like 20 or 30 %. When that happens, Windows wants me to format the card, 'cause: no valid file system found.
They are still recoverable via tools, but still it's annoying. If I copy them first and delete them afterwards on the card - no problem at all.

I'd be happy if someone has a a permanent fix for that/explanation why this is happening.

Have you checked the file system for errors?

You can right click the corrupted NTFS partition in Windows File Explorer, and select "Properties". Then navigate to "Tools" tab and click "Check" under "Error Checking". That option will check the selected partition for file system error.

Well, when it's not damaged and Windows wants me to format it: No errors at all. Even a h2testw check: no errors.

But when I delete everything from that card: Bazinga!
