A system and method for efficiently identifying track squeeze errors (TSEs) of a disk of a disk drive during a testing process for the disk drive is disclosed. The method includes reading servo bursts from a track of the disk, utilizing a modeled scan variable, and determining a gain comprising a ratio of a first matrix A and a second matrix B. TSEs associated with the SWEs of the servo bursts are determined for the track. The TSEs are determined as a product of the gain and a measured scan variable wherein the measured scan variable is calculated as being the difference between a measured scan value and an estimated nominal scan value.
