Assessement of current health of hard disk drives

2009 IEEE International Conference on Automation Science and Engineering, 2009
After investigating several of different degradation signatures that can potentially characterize aging and failure of computer hard disk drives (HDDs), we identified that reported uncorrect, hardware ECC recovered and read write rate parameters can provide good degradation signature for assessing the condition and remaining useful life of HDDs.

Survey on energy-efficient hard drive disks

2017 International Conference on Computing, Networking and Communications (ICNC), 2017
Energy consumption has been brought to the forefront in the past decade. Energy efficiency is being considered in all phases of hardware and software design and implementation. High energy consumption is becoming an increasingly large burden for organizations and institutions hosting large-scale computing systems.

Wise drives [hard disk drive]

IEEE Spectrum, 2002
Considers how smarter disk drives could herald speedier data mining, tighten computer security, and improve data storage reliability, but only if drive and computer makers and software designers can agree on new interface standards.

Impulsive disturbance rejection in hard disk drives

2010 11th International Conference on Control Automation Robotics & Vision, 2010
This paper proposes filtering methods to cancel the impulsive disturbance contained in position error signal (PES) in hard disk drives (HDDs). The impulsive disturbances may be observed as a few single sudden changes or some consecutive changes in PES. The filtering includes impulsive disturbance identification and estimation.

Adaptive-repetitive control of a hard disk drive

2007 46th IEEE Conference on Decision and Control, 2007
This paper presents a control scheme intended to target both the non-repeatable and repeatable runout disturbances affecting the dynamics of a hard disk drive (HDD). The design can be broken up into three stages. The first stage consists of a LTI feedback controller designed using classical techniques.

Hard Disk Drives Control in Mobile Applications

Journal of Systems Science and Complexity, 2007
In this paper, control design is investigated for hard disk drives in mobile applications with unknown external arbitrarily fast time-varying disturbances. The disturbances can be estimated with exponential accuracy using the proposed disturbance observer based on a series of integral filters.

Adaptive Tuning and Control of a Hard Disk Drive

2007 American Control Conference, 2007
This paper deals with the implementation of adaptive tuning and control on a computer hard disk drive (HDD). A model-based adaptive loop is added to a LTI stabilizing controller to minimize the position control error of the HDD head. This adaptive loop may be used in either of two modes: control tuning (CT) or real-time fully adaptive control (RTFAC ...

Hard disk drive multimedia

The Electronic Library, 1993
A multimedia effect can be provided by programs which use the hard disk drives of PCs. Knowledge Adventure and Science Adventure are two programs providing a multimedia experience without the use of CDROM. Knowledge Adventure provides information on general subjects while Science Adventure concentrates on science material with text taken from a book by

Computing the aeroelastic disk vibrations in a hard disk drive

Journal of Fluids and Structures, 2008
Abstract The turbulent flow of air caused by the spinning of a single disk inside a typical hard disk drive casing is calculated using large eddy simulation (LES). The pressure acting on the disk is recorded as a function of time and is used to compute the vibrations of the spinning disk using a self-developed hybrid-spectral finite-difference code ...

A Low-Power Write Driver for Hard Disk Drives

IEICE Transactions on Electronics, 2005
This paper describes a new low-power write driver circuit for mobile hard disk drive preamplifiers. To achieve low power consumption, we developed a write driver circuit with a single-stage MOS transistor as the current driver, which both switches and controls the write current.
