International ClassesG06F 003/00G06F 001/00 G06F 001/16 AbstractA computer system having a removable hard disk drive is disclosed. The interposer card is modified to receive a docking bay which receives a cartridge which contains a hard disk drive. The docking bay includes the male portion of a zero insertion force connector and a first circuit board to which connects to the interposer card of the computer. The first circuit board also includes circuit paths between the male portion of the zero insertion force connector and the end which connects to the interposer card of the computer. The first circuit card also includes circuitry which allows "hot plugging" of the hard disk drive to the bus of the computer and which also acts as a lockout to prevent writing to the removable hard disk drive until after the computer system has been rebooted. The docking bay also includes a spring mechanism for ejecting the cartridge. A finger lever holds the cartridge in place and can be lifted to eject the cartridge. A hard disk drive is placed within a cartridge which includes a second printed circuit board. Attached to the second printed circuit board is the female portion of a zero insertion force connector.Other References
