|Using KillDisk / Preferences|
KillDisk offers different Disk Examination Options, depending on user needs. Each examination type has its' own strengths and weaknesses, mainly tradeoffs between time and thoroughness. Any of the examination types can be performed on an entire disk, or a selected segment.
Examination options are required for disk integrity examination and optional for disk erasure but can be used to sort away faulty disk from following processing in sequence.
To examine disk integrity the following three algorithms are used:
Based on examination results disks could be "graded" depending on amount of failed sectors. Specific grade attributes can be set on Disk Examination Grades page of application preferences. Further Disk Erase command can be executed or canceled based on current disk's grade.
For each grade, you may select the Green, Yellow, or Red to represent the disk grade visually. Multiple grades may share the same color
