Hot to mount external drives consistently

lsblk #list them again
lsblk -f /dev/sda1 /dev/sdb2 #see the format and the UUID of a couple of blocks
df -h /dev/sda1 #you will see if its mounted

sudo apt install ntfs-3g

sudo nano /etc/fstab #forever
UUID=some-uuid /mnt/data_ntfs_500 ntfs-3g defaults,uid=1000,gid=1000,umask=0022 0 1
UUID=some-uuid-of-your-drive /mnt/ext4_mount_point_folder ext4 defaults 0 1

For one time:

sudo mkdir -p /mnt/data_ntfs_500
sudo mount -t ntfs /dev/sda1 /mnt/data_ntfs_500/ #example with ntfs

sudo mkdir -p /mnt/data_ext_2tb
sudo mount -t ext4 /dev/sdb2 /mnt/data_ext_2tb/ #example with ntfs
