A convertible chassis system for receiving a plurality of storage drives includes a chassis that includes a plurality of bays for receiving the storage drives. The convertible chassis also includes a reversible key that is removably affixed to the chassis body in either a first orientation or a second orientation. Each orientation provides a different key guide within the plurality of bays that either allows the storage drives to be received into or rejected from the bays of the chassis.

Disclosed herein is an apparatus and/or device to scrape a hard disk drive (HDD) to completely and permanently erase, remove, and/or destroy digital and/or electronic data and/or information stored on and/or written to the HDD without using and/or necessitating the use of external induction. The apparatus includes a first part of a HDD scrapper mounted on an arm of the HDD and a second part of the HDD scrapper mounted on a scrapper head. The apparatus also includes a turner that simultaneously permits a turning operation of magnetic platters of the HDD and the HDD scrapper. The first part, the second part, the arm, the scrapper head, the turner, and the magnetic platters are included in an enclosure of the HDD.

A quick-releasing mechanism is applied to an electronic apparatus. The quick-releasing mechanism includes a central axle, an ejecting component, and a locking component. The ejecting component is slidably disposed on the central axle, and has a supporting portion configured to support a bracket, and a first inclined guiding structure disposed under the supporting portion. The locking component includes a base, a second inclined guiding structure, a pressing portion, and a pushing portion. The base is rotatably disposed on the central axle. The second inclined guiding structure is disposed on the base and slidably abuts against the first inclined guiding structure to lift and lower-down the supporting portion. The pressing portion is disposed on the base to clip the bracket with the supporting portion. The pushing portion is disposed by the base and is pushed for rotation of the base.

A base plate is arranged to define a portion of a housing of a hard disk drive, and includes a base body defined by casting, and an electrodeposition coating film arranged to cover a surface of the base body. The surface of the base body includes a coated surface covered with the electrodeposition coating film, and a flat worked surface exposed from the electrodeposition coating film. The worked surface may include a gate position to which a gate has been connected at the time of the casting. At least a portion of the worked surface is covered with an impregnant.

An air intake control system can consist of an aero-acoustic assembly positioned within an enclosure. The aero-acoustic assembly may have an intake occupied by a plurality of louvers with each of the plurality of louvers configured to move between open and closed positions in response to airflow passing through the intake.

The embodiments herein describe a function module that is removably mounted in a chassis. For example, the chassis may be a server chassis which stores a plurality of blade servers which uses hardware components and a fan module mounted in the function module to increase the storage capacity or computing performance of the blade servers. The function module can include PCIe cards, GPU cards, hard drives, and the like which are communicatively coupled to the blade servers in the chassis. In one embodiment, the function module is slidably mounted onto the chassis so that when pulled by the system administrator, the function module slides out of a front or rear side of the chassis. Doing so provides room for the system administrator to then add and/or remove the hardware components and the fan module mounted in the function module.

A system for storing data includes a discrete cooling module that can enable discrete cooling of mass storage devices installed in the chassis interior of a data storage module coupled to a rack. The discrete cooling module includes an air moving device and an air cover. The air moving device can induce and airflow through the chassis interior of the data storage module to remove heat from heat producing components of mass storage devices installed in the chassis interior. The air cover directs the airflow through the chassis interior. The discrete cooling module can isolate rotational vibrations generated by the air moving device from the mass storage devices installed in the chassis. Partial isolation can include indirectly coupling the discrete cooling module to the chassis via directly coupling with the rack.
