An apparatus and method for attaching a data storage device to a stationary planar support surface using an attachment member having a first side attached to the data storage device and a second side operable to attach to the stationary planar support surface. The needle comprises a needle body portion, a closed pointed tip portion, and an inner lumen extending through said support member and into said protruding needle. In the preferred embodiment the device can give results for both males and females by providing gender-specific scales on either face of the instrument. The first support point connection element is spaced a first distance from the hoist connection element, and the second support point connection element is spaced a second distance from the hoist connection element. After the completion of each read identification code iteration, the host adjusts the controlled variable based upon the responses received in the previous iteration. A standard pre-determined value factor may be applied to the SER for each party for easy of comparison.
