The Implementation of Hard-Disk Protection Method Based on Disk Filter Driver

In this paper, it analyzes the working mechanism for the hard disk protection based on the current disk filter driver. The core ideology of the mechanism is to redirect the I/O request packet to the disk operation and to restore data automatically after restart the system in the case of transparent operating system to its upper storey. Also, it specifically analyzes the safety trouble by new vi...

Emerging Trends in Data Storage on Magnetic Hard Disk Drives

11 INTRODUCT ION The magnetic hard disk drive (HDD) plays an important and extremely useful role in every information processing system; in fact this role is constantly growing as a result of advances in capacity, performance and price. Since the first HDD was introduced in 1956, this device has been the recipient of significant additional technology innovations which have extended its value. I...

A Self-tuning Robust Track-following Control of Sampled-Data Hard Disk Drive Servo System

This paper presents a self-tuning scheme based on response surface method (RSM) to find the optimal finite impulse response (FIR) Youla parameter for an observer based state feedback track-following controller that minimizes the 3 times standard deviation of the PES in an HDD servo system. All the tested Youla parameters to construct the response surface were selected within a robust stable reg...

Exploiting Commodity Hard-Disk Geometry to Efficiently Preserve Data Consistency

In the last couple of years, hard-disk technology has experienced an unjustified progressive boost of the built-in cache size, affecting both the power consumption and the reliability of stored data. Large built-in caches offer limited benefits in terms of performance with respect to the smaller ones. Moreover, they need to be kept in write-through mode to preserve data in case of a power failu...
