    When the computer go to sleep and then turn on, the external HDD always disconnected which cause some issues. Are there any way to prevent this issue?

    System Preference > Energy Saver
    Uncheck "Put hard drives to sleep when possible"

    There is a known issue with this. If it's disconnecting it might not be related to the Energy Saver settings.
