This problem occurs when you don't remove the hard disk safely i.e just plug out of the system or Arch Linux sometimes fails to mount NTFS file format. Well not to worry. this issue is fixed in the video. all you need to do is run these commands in terminal while the hard disk is plugged-in in your system..
sudo modprobe usb_storage
sudo gpasswd -a $USER wheel
sudo gpasswd -a $USER storage
sudo gpasswd -a $USER disk
sudo gpasswd -a $USER users
sudo pacman -S ntfs-3g or yay -S ntfs-3g
sudo mkdir -p /mnt/mountpoint
sudo chown $USER /mnt/mountpoint
sudo mount -t ntfs-3g /dev/your_NTFS_partition /mount_point
(to check your partition type lsblk)
sudo nano /etc/fstab
/dev/sdb1 /mnt/mountpoint ntfs-3g uid=archiman,gid=users,noauto,umask=0022 0 0
(to save and exit Ctrl + o & Ctrl + x)
*NOTE : change the uid for your system.*
