Supporting bracket assembly for drawer-type hard-disk drive
 An assembly for a drawer-type hard disk drive comprising a cartridge in which a hard disk is mounted, and a supporting mount for receiving the cartridge. The cartridge has a power switch, a master/slave switch, a socket connector and a converting circuit card. The supporting mount is of a size such that it fits in the backup drive of a computer and it has a master/slave switch, a D-type connector, a circuit board, a power supplying slot and a jumper such that when the cartridge is inserted into the supporting mount, the socket connects to the connector. The supporting mount has an opening through which the cartridge is inserted and has guiding plates in its sidewalls which engage with guiding slots on the sides of the cartridge. The power switch has a locking latch which extends through a retaining hole on the supporting mount when the power switch is switched on, thus preventing removal of the cartridge, and which retracts when the switch is switched off, thus enabling easy removal of the cartridge. The master/slave switches allow the build-in hard drive and the add-on hard disk drive to be readily set in different operational modes. Furthermore, the cartridge is also connectable to a PCMCIA card for use with notebook computers so that the cartridge can be easily transferred from one type of computer to another.
