  • Patent number: 10102883
    Abstract: A hard drive disk carrier for reducing airflow-induced vibration of a hard disk drive includes a bracket assembly configured to removably secure the hard disk drive to a receiving component within an enclosure. The bracket assembly is configured for substantially exposing major surfaces of the hard drive to yield exposed surfaces and for mounting within the enclosure so that a first end of the hard disk drive faces the first end of the enclosure and a second end of the hard disk drive faces the second end of the enclosure. The bracket assembly also includes at least one end member associated with the second end of the hard disk drive. The carrier also includes an airfoil assembly with one or more louvers configured to extend from at least the second end of the hard disk drive and partially cover at least one of the exposed surfaces.
