A vacuum scavenged spindle and disk clamp assembly decreases particulate contamination during testing and manufacturing of disks such as hard drive platters. A vacuum shroud is sealed to a casing and fitted to a clamp body attached to or integral with the spindle rotor, with the spindle rotor and the clamp body being rotatable. A first scavenging passageway pulls airflow from an interior region of the vacuum shroud, including particulates scavenged from the air bearing between the spindle rotor and the spindle stator. A second scavenging passageway extends from the interior region of the vacuum shroud through the clamp body to a hollow core of the disk clamp. A further scavenging passageway extends through the clamp body to a clamping region. Particulates from the spindle clamp are scavenged by airflow through the further scavenging passageway and the second scavenging passageway. A grounding brush may be attached to the vacuum shroud.
