 *
 *   THE REQUESTED DRIVE WAS IGNORED. The row was chosen with

 *   precisely because they expect one answer per path.
 *
 *   A DRIVE WITH NO MEDIA reports blank Size and FreeSpace -- an empty card
 *   reader or optical drive. `parseInt('')` is NaN, which flowed into `used`
 *   and a NaN usagePercent that nothing rejected.
 *
 * @param output Raw command output.
 * @param path The path whose drive is wanted; a path with no drive letter takes
