Hard drive diagnostics using S.M.A.R.T. technology in Kaspersky for Mac
The article concerns Kaspersky Standard, Plus.
The S.M.A.R.T. diagnostics technology is used in Kaspersky for Mac to track and predict hard drive errors. For reasons why running S.M.A.R.T. diagnostics might be unavailable, see Online Help.
By default, hard drive diagnostics runs 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 for analyzing hard drive condition and performance
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. |
What to do if problems were detected in the hard drive performance
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 get this notification:
- during the warranty period of your computer or hard drive, contact the seller to have your hard drive replaced.
- when warranty has already elapsed, contact a computer or hard drive repair center once you have backed up your files.
If you’re not sure back up your files, see Online Help.
