A flaw scan system for detecting a location of first and second types of location specific anomalies on a storage disk of a hard disk drive comprising a write system, a read system, and first and second anomaly location systems. The write system writes a first set of bits to the storage disk in first and second data patterns. The read system reads the first set of bits from the storage disk. The first anomaly location system determines locations of the first type of location specific anomaly based on the first data pattern. The second anomaly location system determines locations of the second type of location specific anomaly based on the second data pattern.
