WebJan 19, 2012 · 3. Unfortunately, the problem is that the only way to securely erase data that resides on a disk is to "wipe" any unused sectors on the drive. This works okay for file-based solutions, as when you delete a file, the OS marks the sectors as being available (ie: unused) and consequently, you can wipe them. WebConclusion. Guttman’s L4 provides a reliability coefficient that is relatively simple to understand and can be easily computed using code written in R. In addition to the code provided in the appendix of this paper, the Lambda4 package by Tyler Hunt also appears to provide a robust estimation method. rpp mengenal microsoft word
