Hard drive smart utility5/11/2023 ![]() The drive manufacturer determines which attributes will be monitored on a particular drive model based on that model’s characteristics and previous reported failures of the technology used in the drive. The user or system administrator can then take precautions to prevent data loss. When the BIOS or software polls the drive and detects the SMART error, it will notify the user that a problem has been detected. If a problem is detected-that is, if an attribute value approaches or falls below its threshold value-a SMART error occurs and an alert is added to the status information. ![]() The software will poll all drives in the system at a set time interval. Then, the drive makes its status and attribute information available to the BIOS or software that polls it for this information. The hard drive monitors certain mechanical and electronic characteristics (attributes) and compares their values to the drive manufacturer’s base (threshold) values to determine if a hard drive is beginning to fail or is currently failing. It is implemented with a SMART-compliant hard drive and either firmware included with your system’s BIOS or software provided by a third-party utility. SMART attempts to detect problems that worsen over time and that might eventually lead to complete drive failure. SMART is a nonproprietary standard that allows for predictive failure analysis of hard disk drives. SMART (self-monitoring analysis and reporting technology) is a feature of most modern hard drives that attempts to do just that. If you received some kind of alert that a hard drive was about to fail, you might be able to prevent data loss and minimize downtime. Since hard drives often contain critical data that has yet to be backed up, it would be very useful to be able to predict hard drive failures before they occur. Nevertheless, their reliance on moving components makes them vulnerable to mechanical failure and therefore more likely to fail than a solid-state device. In this Daily Drill Down, Rodrigo Zamora shows us ways SMART can help.ĭespite their reputation as being delicate, modern hard drives are incredibly reliable devices. Having a little advanced warning would be nice so that you could back up the data before it?s gone forever. ![]() A failed hard drive can be very unsettling.
