Claim One:
1. A method comprising: in a data storage device that includes a non-volatile memory and a controller, wherein the non-volatile memory includes a word line coupled to a plurality of storage elements, performing by the controller: detecting a condition associated with a defect in the word line; determining an estimated location of the defect by: initializing a location estimate of the defect based on a midpoint of the word line; partitioning the plurality of storage elements into a first partition and a second partition about the midpoint; and based on a comparison of a first parameter associated with the first partition and a second parameter associated with the second partition, adjusting the location estimate to increase a parameter difference between partitions of the plurality of storage elements; determining a first subset of the plurality of storage elements and a second subset of the plurality of storage elements based on the estimated location of the defect; and determining a first read threshold for the first subset and a second read threshold for the second subset, wherein reading data from the word line using at least one of the first read threshold or the second read threshold reduces an error rate associated with the data as compared to not using the at least one of the first read threshold or the second read threshold.
