Disk Drive Failure Factors
نویسنده
چکیده
Modern disk drives have become highly complex with increasing demands on high throughput, high reliability, high capacity, and low cost most of which are typically mutually exclusive. This paper takes a look at the reliability aspect of disk drives, and, more specifically, factors that cause a drive to fail. Failures fall into three main categories: hardware, software, and process. Many of the frequent factors are given, focusing on data thrashing, disk age, and hot spots.

Failure Trends in a Large Disk Drive Population
It is estimated that over 90% of all new information produced in the world is being stored on magnetic media, most of it on hard disk drives. Despite their importance, there is relatively little published work on the failure patterns of disk drives, and the key factors that affect their lifetime. Most available data are either based on extrapolation from accelerated aging experiments or from re...
متن کاملBayesian approaches to failure prediction for disk drives
Hard disk drive failures are rare but are often costly. The ability to predict failures is important to consumers, drive manufacturers, and computer system manufacturers alike. In this paper we investigate the abilities of two Bayesian methods to predict disk drive failures based on measurements of drive internal conditions. We first view the problem from an anomaly detection stance. We introdu...
متن کاملFretting Wear between a Hollow Sphere and Flat Surface
Wear particles in a hard disk drive may cause the head/disk interface to fail. We have experimentally investigated wear particle generation resulting from fretting wear between the dimple on the suspension and the gimbal spring. We have found that increasing the normal load as well as using a low friction coating reduces the formation of wear particles. INTRODUCTION Examination of failed hard d...
متن کاملImproved disk-drive failure warnings
Improved methods are proposed for disk-drive failure prediction. The SMART (Self Monitoring and Reporting Technology) failure prediction system is currently implemented in disk-drives. Its purpose is to predict the near-term failure of an individual hard disk-drive, and issue a backup warning to prevent data loss. Two experimental tests of SMART show only moderate accuracy at low false-alarm ra...
متن کاملDynamic characterisation of the head-media interface in hard disk drives using novel sensor systems
Hard disk drives function perfectly satisfactorily when used in a stable environment, but in certain applications they are subjected to shock and vibration. During the work reported in this thesis it has been found that when typical hard disk drives are subjected lo vibration, data transfer failure is found to be significant at frequencies between 440Hz and 700Hz, at an extreme, failing at only...
