Improved 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 کاملDisk Drive Failure Factors
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 ...
متن کاملFailure 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 کاملThe Forgetful Disk Drive
Approaches to data protection have traditionally focused on physical security and/or cryptographic security, but the automatic deletion of data as a form of protection has not been widely employed. However, a vast amount of data is stored that has only a limited useful life and presents a risk to privacy and security after that time period. Approaches to data deletion can be broadly classified ...
متن کاملAutomated Disk Drive Characterization
DIXtrac is a program that automatically characterizes the performance of modern disk drives. This report describes and validates DIXtrac's algorithms, which extract accurate values for over 100 performance-critical parameters in 2 { 6 minutes without human intervention or special hardware support. The extracted data include detailed layout and geometry information, mechanical timings, cache man...
