bash storage_test_2

Description

  • Test Type: storage_test_2 performs a comprehensive readability test, scanning the entire storage device for errors.
  • In-Depth Analysis: This test is more extensive than storage_test_1 and is designed to detect less obvious storage issues.

Examples

Run an Extensive Readability Test

bash storage_test_2

This command begins a detailed scan of the storage device to identify any read errors or data integrity issues.

Additional Information
