Methods and apparatus are provided for detecting a syncMark in a read channel, such as a hard disk drive. A syncMark is detected in a sector in an iterative read channel by obtaining a sector signal from a storage media, the sector signal comprising a first syncMark, data and a second syncMark substantially at an end of the sector; determining whether the first syncMark is detected in the sector signal; searching for the second syncMark if the first syncMark is not detected in the sector signal; and detecting and decoding the sector signal based on a detection of the second syncMark. The second syncMark may be positioned, for example, following data in the sector signal. The second syncMark can be searched for in a window within the signal sector that is based on an estimated location of the first syncMark.
