How to mount and detach a new hard disk in a vmwarevm in a Linux System

In a vmwarevm, mount or detach a new hard disk in a Linux system: 1. Start the vm, choose vm> Settings, and add a SCSI disk in the Wizard. Go to the Linux system. 2. fdisk-l will see a new setting. If you have a hard disk (sda1, sda3. ..), the newly added disk should be (/dev/sdb ).
