Abstract
The present invention provides an improved method and system for link detection and handling. The method includes detecting one of the plurality of link sectors; generating an interrupt signal; determining a buffer method selection; buffering the plurality of data sectors only, if a link skip buffer method is selected; and buffering the plurality of data sectors and the plurality of link sectors, except for a link block, and allocating a sector in a buffer for the link block, if a link buffer method is selected. The present invention provides a hardware approach to link sector detection and handling. Instead of passing the data to a system software prior to link sector detection, the method and system in accordance with the present invention performs the link sector detection in the controller hardware. When the controller detects the link sectors, it automatically either skips or buffers the link sectors depending upon the configuration of the controller. By performing the link sector detection in hardware, significant processing time is saved.
