ABSTRACT:
Disclosed is a method for determining an exact address of sectors retrieved from a media that is formatted in a headerless format. The method includes the acts of requesting a desired sector. Associating a seed value to the desired sector. Retrieving an initial sector from the media in response to the requested desired sector. Calculating an error detection and correction over the initial sector and the seed value that is associated with the desired sector to produce a seed error pattern at a seed location. The method further includes, in one embodiment, the act of performing a logical XOR operation between the seed error pattern and the seed value to produce an exact address of the initial sector that is retrieved from the media. Once the exact address of the initial sector is ascertained, a transition may be made to the desired sector. On the other hand, the data beginning at the received sector may be used.
