How to mount the U-disk (mobile HDD) to the Ubuntu system

How do you mount the U-disk (removable hard drive) to the Ubuntu system as you would a disk? The following three steps make it easy to handle:

1: Open Ubuntu shell, enter: fdisk-l (to log in as root), find the corresponding U-disk mount name, as our SDB1

ext =/DEV/SDB1
2. Set up a local directory mkdir/mnt/d to mount the U disk;
3. Mount the mobile U-disk to the/MNT/DMOUNT-T ntfs/dev/sdb1/mnt/d/
4. Access to the contents of the/mnt/d is the operation of the U-disk.
