Your drive is probably totally fine. This almost always happens when the partition is formatted as FAT32. FAT32 has a hard 4GB file size limit, so even though you’ve got 200GB free, Windows refuses to copy a 12GB movie file.
You can check by right clicking the drive > Properties. If it says FAT32, that’s the issue.
The easiest fix is converting it to NTFS without wiping the drive. Open Command Prompt as admin and run:
convert X: /fs:ntfs
Just replace X with your drive letter.
Small heads-up though: back up anything important first, just in case. The conversion usually works fine, but it’s better not to risk important files.
If the partition is empty anyway, honestly it’s faster to just right click the drive > Format > choose NTFS or exFAT instead.
