Systems and methods for missed media sector alignment

A data processing system, the system comprising:

• a first sync mark detector circuit operable to apply a first sync mark detection algorithm to search a received media sector and overhead for a second sync mark after a failure to identify a first sync mark, wherein the received media sector includes a first fragment set corresponding to a first codeword, a second fragment set corresponding to a second codeword, and wherein the first fragment set is shuffled with the second fragment set to yield an intermixed fragment set;
• a second sync mark detector circuit operable to apply a second sync mark detection algorithm to search the received media sector and overhead for the second sync mark, wherein the second sync mark detection algorithm is more robust than the first sync mark detection algorithm;
• an anchor point identification circuit operable to identify an anchor point in the received media sector;
• a retry controller circuit operable to cause a re-read of the received media sector and overhead when the first sync mark detector circuit fails to identify the first sync mark, and to align the received media sector to a forced sync mark at a location calculated based upon a first location of the anchor point and a second location of the second sync mark to yield an aligned media sector;
• and
• a data processing circuit operable to recover an original user data set from the aligned media sector.
