Abstract

A disk attachment may use inverted check fields to flag unreliable data on an associated file. Unreliable data is generated by the data recovery procedures used during alternate sector assignment programs. Alternate sector assignment is done when it becomes impossible to use a given sector on the disk surface due to such things as grown surface defects.
