PROBLEM TO BE SOLVED: To provide a data transferring device, a computer device, a device, and a docking station capable of stabilizing the signal waveform at the time of transferring data. SOLUTION: In this PC system, at the time of transferring data between a host part 10 and an HDD device 40 or a CD-ROM drive device 30 through an IDE bus 20, a signal is fed back from the reception side of the data through a feedback circuit 50 to the transmission side of the data so that the through- rate of a signal to be transmitted at the transmission side can be changed based on this. Moreover, when the CD-ROM drive device 30 or the HDD device 40 is attached or detached while the power source of the PC system is applied, calibration is performed by a calibration performing part 83 so that the through- rate of a signal to be transmitted at the transmission side can be changed.
