Abstract: In order to transmit easily the information in a hard disk of a first computer to that of a second computer having a different system from the first computer, a hard disk compatible system is provided for directly moving a hard disk for notebook computer to a desk top computer or from a desk top computer to a notebook computer by means of a holder without the use of floppy disks. The system includes a body wherein guide rails are formed to be fitted on a desk top computer, and, corresponding to this, a bracket having bracket guides is fixed on it. Attaching a hard disk guide and an interface board thereto, an inserting portion suitable for the size of a hard disk of the notebook computer is fitted on the front surface of the bracket in such a manner that the hard disk can be easily and snugly inserted and removed to facilitate the interchange of the information, in accordance with this invention.
