Wait!!! Make sure you run only a non-destructive fsck. If the non-destructive fsck shows no problem, do the following...
First run the sync command. The sync command forces all caches to be written to their respective files. If they're on a removeable drive, my next step after sync would be to unmount the drive. Then physically disconnect it. Then physically reconnect it. Then remount it. Then do your df -h. Also, if your removeable drive is some sort of SSD, you might need to do fstrim, although I swear I remember space deleted but not yet trimmed doesn't count in df. But I could be wrong.
