Abstract: The present invention relates to a method for providing a master-slave hot-swapping apparatus and mechanism for use with an ATA bus. A bus controller and a bus separator are employed for isolating the hot-swapping apparatus and the host system, and a power supply switch is used.

Abstract: The present invention relates to a method for providing master-slave heat-swapping apparatus and mechanism in a mono-ATA bus, which mainly consists a bus controller and a bus separator for isolating the signals in the processing of heat swapping from the heat-swapping apparatus and the host system and for detecting the power supply and heat swapping process of mast and slave heat swapping apparatus and the host system for renewing a new one matter without cut-off the power supply as any of them is dysfunction.

Abstract: The present invention relates to a method and a structure for ATA bus protocol compatible time-division multiplexing data transfer of single-bus and multi-drive. It mainly consists of a primary ATA bus arbiter and several ATA/HD bridges and concurrent ATA master drives. The primary ATA bus arbiter combines the bus requests of ATA bus masters to complete time-division multiplexing on the host side and allocate the ATA bus application. The ATA/HD bridges are used to respond to the on-line requests of the bus masters by switching the time-division multiplexing on the target side and resolve the possible bus contention that may be generated when two or more ATA drives are acting simultaneously. The concurrent ATA master drives will default all ATA drives as master drives under a bridge structure to allow them to become independent to each other so as to carry out respective commands and await requests from the main system individually.
