Self Monitoring

Prognostics and health management of computer hard disk drives is beneficial from two different angles: it can help computer users plan for timely replacement of HDDs before they catastrophically fail and cause serious data loss; it can also help product recover facilities reuse hard disks recovered from the end-of-life computers for building refurbished computers. This paper presents a HDD health assessment method using Self-Monitoring, Analysis, and Reporting Technology (SMART) attributes. It also presents the state-of-the art results in monitoring the condition of hard disks and offers future directions for distributed hard disk monitoring.

Magnetic Hard Disk

AbstractMagnetic recording has progressed dramatically over the last 50 years, with an increase of almost eight orders of magnitude in the amount of information stored per unit area of disk space.Two key enablers of this progress have been the recording medium and the read-back head.This article reviews the current state of the art in multilayer thin-film longitudinal recording media and giant magnetoresistive (GMR) read heads, with particular emphasis on the nanostructured magnetic materials that are key to today's high-performance hard disk drives.

Usage Phase

Data collected during product lifecycle phases ranging from the beginning of Life (BOL), to the middle of life (MOL) and the end of Life (EOL) assist designers to make informed decisions in various operational and strategic levels. The specific focus of this paper is to show that the data collected during the usage phase of Hard Disk Drives (HDDs) can be used to identify the failure rates of HDDs. Two sources of data were applied: quantitative data extracted from Self-Monitoring Analysis and Reporting Technology (SMART) software, and qualitative data collected from consumer reviews. The data were analyzed to predict the most reliable HDDS available in the market. Some of the important factors to be considered during manufacturing of an HDD are suggested based on the results obtained.
