Abstract
Various illustrative aspects are directed to a data storage device comprising data tracks N and N−1, and one or more processing devices, configured to identify, during a track write on the data track N, a write abort event based upon an expected risk for the data track N−1 exceeding a risk threshold, read one or more sectors of the data track N−1 and collect one or more corresponding sector metrics, verify the one or more sectors based upon the collected sector metrics, wherein the verifying comprises assigning each of the one or more sectors as one of a readable or a non-readable sector, and continue the track write on the data track N upon determining each of the one or more sectors is a readable sector, or recovering and relocating the data track N−1 based on determining at least one of the sectors is a non-readable sector.
