Data storage device aborting write operation based on accumulated track squeeze metric for adjacent data track

A data storage device is disclosed comprising a head actuated over a disk comprising a plurality of data tracks, including consecutive data tracks N−1 and N. A first write to data track N is performed using a first position error signal (PES) representing a position of the head relative to the data tracks. A track squeeze metric is generated for data track N−1 based on at least the first PES of the first write. The track squeeze metric for data track N−1 is accumulated during the first write, and the first write is aborted when the accumulated track squeeze metric for data track N−1 exceeds a first threshold.
