Examine Disk Integrity concept

Disk integrity examination is a critical diagnostic process that verifies the health and reliability of storage media by systematically reading and analyzing disk sectors. This process helps identify potential hardware failures, bad sectors, and other issues that could compromise data integrity before they lead to data loss. KillDisk Industrial provides multiple examination methods to balance thoroughness with time efficiency, allowing you to choose the appropriate level of scrutiny based on your specific requirements.

The application employs three distinct examination algorithms, each designed for different use cases. Partial examination analyzes a specified percentage of the disk by reading equally segmented portions within the selected area, providing a representative sample of disk health in a time-efficient manner. Partial random examination reads a predefined number of randomly distributed sections across the selected area, offering statistically relevant coverage while minimizing examination time. For the most comprehensive assessment, Read each sector in selected area examines every sector within the chosen area, making it the most thorough but also the most time-consuming option.

In addition to sector-level examination, KillDisk Industrial can analyze disk S.M.A.R.T. information attributes. SMART data provides valuable insights into drive health by monitoring various parameters such as read error rates, spin-up time, temperature, reallocated sector counts, and other critical indicators that predict potential drive failures. By combining both physical sector examination and SMART attribute analysis, you can obtain a comprehensive assessment of disk integrity and make informed decisions about drive reliability and data security.

Based on examination results, disks can be graded depending on the number of failed sectors. Specific grade attributes can be set on the Examine Grades page of the application preferences. The Disk Erase command, for instance, can then be executed or canceled based on the current disk's grade.
