Abstract

A system for impairing at least one pair of data platters stacked. An alignment device is pivotably mounted; upper and lower arms of the alignment device are spaced apart from and extend parallel to one another. The alignment device is movable between a stowed position in which the alignment device is spaced apart from the data platters to an impairment position in which the upper and lower arms of the alignment device overlay at least an edge of the data platters. The upper arm includes an opening for receiving an impairment tool, the opening being generally aligned with an impairment opening formed in the enclosure when the alignment device is in the impairment position. The impairment tool is inserted through the impairment opening formed in the enclosure and the opening in the upper arm for engaging a surface of the data platters to impair the data platters.
