  • Patent number: 7636237
    Abstract: An intelligent locking device comprises a microprocessor, a locking element and a control button electrically connected to the microprocessor respectively. The locking element locks a removable HDD to a computer. The control button generates trigger signals in response to manual push thereon. When receiving the trigger signal, the microprocessor detects whether there is data transferring between the removable HDD and the computer, if there is data transferring, the microprocessor terminates data transferring and then sends a driving signal to the locking element; if not, the microprocessor directly sends a driving signal to the locking element. When receiving the driving signal, the locking element releases the lock between the removable HDD and the computer to permit the removable HDD to be safely ejected. Meanwhile, a removable HDD receiving system with the locking device and a method for preventing the removable HDD from being wrongly ejected from the receiving system are disclosed.
