Abstract
A method for monitoring working states of hard disks of a system of hard disks in a hard disk module includes a hard disk controller and a complex programmable logic device (CPLD). The hard disk controller and CPLD communicate with the hard disk module. The CPLD receives output signals from the hard disk controller and determines whether rise and fall changes in a clock signal of each output signal are steady. When a level change of the clock signal of one output signal is steady, the CPLD decodes the one output signal. When a level change of the clock signal of one output signal is not steady, the CPLD will stop decoding the one output signal. A related method is also provided.
