"By default, the total expected lifetime of a hard disk in perfect condition is defined as 5 years (running every day and night on all days). The raw value of this attribute shows total count of hours (or minutes, or seconds, depending on manufacturer) in power-on state. If this attribute is decreasing, it is a sign of problems in the mechanical subsystem.Ĭount of hours in power-on state. The raw value has different structure for different vendors and is often not meaningful as a decimal number.Īverage performance of seek operations of the magnetic heads. Such a failure may be due to numerous factors, such as damage to a servo, or thermal widening of the hard disk. If there is a partial failure in the mechanical positioning system, then seek errors will arise. (Vendor specific raw value.) Rate of seek errors of the magnetic heads. The function of this attribute is not specified. This value is primarily used as a metric of the life expectancy of the drive a drive which has had any reallocations at all is significantly more likely to fail in the immediate months. Thus, the higher the attribute value, the more sectors the drive has had to reallocate. The raw value represents a count of the bad sectors that have been found and remapped. The spindle turns on, and hence the count is increased, both when the hard disk is turned on after having before been turned entirely off (disconnected from power source) and when the hard disk returns from having previously been put to sleep mode.Ĭount of reallocated sectors. If the value of this attribute is decreasing there is a high probability that there is a problem with the disk.Īverage time of spindle spin up (from zero RPM to fully operational ).Ī tally of spindle start/stop cycles. Overall (general) throughput performance of a hard disk drive. The raw value has different structure for different vendors and is often not meaningful as a decimal number.
(Vendor specific raw value.) Stores data related to the rate of hardware read errors that occurred when reading data from a disk surface.
SSD HEALTH STATUS HOW TO
This tutorial will show you how to check the health and SMART status of all connected local drives to see if they are failing in Windows 10.įor a Windows 11 version of this tutorial, see:Ĭheck Drive Health and SMART Status in Windows 11 It is strongly recommended that users immediately back up their data after receiving a notification. This feature in Option Five is designed to detect hardware abnormalities for NVMe SSDs and notify users with enough time to act. Attempting to recover data after drive failure is both frustrating and expensive.
SSD HEALTH STATUS WINDOWS 10
Starting with Windows 10 build 20226, Microsoft has added new storage health monitoring for NVMe SSDs. See also: Windows 10: Built-in tools for Hard Disk Health check | Microsoft TechNet
SSD HEALTH STATUS SOFTWARE
data indicates a possible imminent drive failure, software running on the host system may notify the user so preventive action can be taken to prevent data loss, and the failing drive can be replaced and data integrity maintained. Its primary function is to detect and report various indicators of drive reliability with the intent of anticipating imminent hardware failures.
(Self-Monitoring, Analysis and Reporting Technology often written as SMART) is a monitoring system included in computer hard disk drives (HDDs), solid-state drives (SSDs), and eMMC drives. How to Check Drive Health and SMART Status in Windows 10
