Hard drive diagnostics using S.M.A.R.T. technology in Kaspersky Security Cloud 20

Latest update: September 12, 2023 ID: 15129

The article concerns Kaspersky Security Cloud — Family and Personal.

The S.M.A.R.T. diagnostics technology is used in Kaspersky Security Cloud to track and predict hard drive errors. A component in Kaspersky Security Cloud analyzes the condition of the hard drive by its S.M.A.R.T. parameters. The S.M.A.R.T. parameters are described below.

Hard drive health check in Kaspersky Security Cloud is performed automatically once a week. If necessary, you can also run it manually.

When the condition of your hard drive worsens, the application will show you a warning so that you can backup your files and avoid data loss. If you receive this message during the warranty period of your computer or hard drive, contact the seller to have your hard drive replaced. If the warranty has already elapsed, contact a computer or hard drive repair center once you have backed up your files.

How to run S.M.A.R.T. hard drive diagnostics

S.M.A.R.T. parameters used when analyzing hard drives in Kaspersky Security Cloud

S.M.A.R.T. parameters are used for analyzing hard drive condition and performance. Each parameter has a threshold value against which the current value is compared.

Parameter value	Description
Read Error Rate	Shows the frequency of errors during disk read operations.
Spin Up Time	Shows the average disk spin-up time from 0 RPM to working speed.
Start/Stop Count	Shows the total number of times a drive has been turned on and off.
Reallocated Sectors Count	Shows the number of reallocated sectors. A sector is marked as reallocated when a read, write or verification error occurs on the disk. The data is moved to a special backup (spare area). When a large number of sectors are reallocated, the data reading speed drops sharply (up to 10% or more).
Seek Error Rate	Determines the rate of seek errors of the magnetic heads. Seek errors will arise there if is a partial failure in the mechanical positioning system, damage to a servo, or thermal widening of the hard disk.
Power-On Hours	Shows the count of hours in power-on state.
Spin-Up Retry Count	Shows the number of attempts to reach the fully operational disk spin speed.
Power Cycle Count	Shows the count of full hard disk power on/off cycles.
End-to-End Error	Shows a count of errors that occurred when transferring data via the drive's cache.
Reported Uncorrected Errors	Shows the count of sectors that were declared as unstable for reallocation for the whole history of the drive. If a sector is declared a unstable for a second time, the value of the attribute will also increase.
Command Timeout	Shows the count of operations that were canceled because their execution time exceeded the drive timeout period.
Temperature	Shows the current disk temperature.
Hardware EСС Recovered	Shows the count of errors that were corrected using ECC (Error Correction Code).
Reallocation Event Count	Shows the number of sector reallocation events.
Current Pending Sector Count	Shows the number of unstable sectors for reallocation to the disk’s spare area.
Uncorrectable Sector Count	Shows the number of unstable sectors detected when testing the disk offline.
Disk Shift	Shows the distance the disk has shifted relative to the spindle.
Percentage Lifetime Remaining	Shows the percentage of time remaining in which the disk will be in working condition.
Media Wearout Indicator	Shows remaining flash memory life (on an SSD).
Average Erase Cycle	Shows the average number of erase cycles.
Host Writes	Shows the number of writes to the NAND memory (Not-And).
Soft Read Error Rate	Shows the frequency of software read errors.
Total Written	Shows the total volume of information on the disk.
Total Read	Shows the total volume of information read from the disk.
Max Erase Cycle	Shows the maximum possible number of disk erase cycles.
Total Erase Cycle	Shows the total number of disk erase cycles.
Available Spare	Shows the amount of spare memory remaining on the disk.
Unknown	A parameter that could not be determined.
