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

Latest update: September 12, 2023 ID: 15562

The article concerns Kaspersky Security Cloud for Mac — Family and Personal.

The S.M.A.R.T. diagnostics technology is used in Kaspersky Security Cloud for Mac to track and predict hard drive errors.

Hard drive health check is performed automatically once a week. You can view the health check report manually at any time. See the Online Help page for instructions.

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

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	The frequency of errors during disk read operations.
Spin Up Time	Average time of spinup from 0 spins per minute to the working speed.
Reallocated Sectors Count	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	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.
Spin-Up Retry Count	The number of attempts to reach the fully operational disk spin speed.
Temperature	Hard drive temperature.
Power-On Hours	The count of hours in power-on state.
Power Cycle Count	The count of full hard disk power on/off cycles.
Hardware EСС Recovered	Number of errors detected and fixed by the ECC memory of the drive.
Reallocation Event Count	Number of sector reallocation events.
Current Pending Sector Count	The number of unstable sectors for reallocation to the disk’s spare area.
Uncorrectable Sector Count	The number of unstable sectors detected when testing the disk offline.
End-to-End Error	A count of errors that occurred when transferring data via the drive's cache.
Reported Uncorrected Errors	The count of sectors that were declared as unstable for reallocation for the whole lifecycle of the drive. If a sector is declared a unstable for a second time, the value of the attribute will also increase.
Command Timeout	The count of operations that were canceled because their execution time exceeded the drive timeout period.
Disk Shift	Distance the disk has shifted relative to the spindle.
Percentage Lifetime Remaining	Remaining lifetime of the hard drive in percents.
Media Wearout Indicator	Information about HD wearout.
Average Erase Cycle	The average number of erase cycles.
Host Writes	Number of writes to the NAND memory (Not-And).
Soft Read Error Rate	Frequency of software read errors.
Total Written	Total volume of information on the disk.
Total Read	Total volume of information read from the disk.
Max Erase Cycle	Maximum possible number of disk erase cycles.
Total Erase Cycle	Total number of disk erase cycles.
Available Spare	The amount of spare memory remaining on the disk.
Unknown	A parameter that could not be determined.
