Abstract: In digital forensics field, data wiping is considered one of the anti-forensics’ technique. On the other perspective, data wiping or data sanitization is the technique used to ensure that the deleted data are unable to be accessed by any unauthorized person. This paper introduces a process for data sanitization from computer hard disk drive. The process was proposed and tested using commercial data sanitization tools. Multiple testing has been conducted at accredited digital forensic laboratory of CyberSecurity Malaysia. The data sanitization process was performed using overwritten method provided by state-of-the-art data sanitization tools. For each sanitization tool, there are options for the wiping technique (overwritten) process. The options are either to wipe using single pass write or multi pass write. Logical data checking in the hard disk sector was performed during pre and post data disposal process for a proper verification. This is to ensure that the entire sector has been replaced by data sanitization bit pattern in correspondence to the selected wiping technique. In conclusion, through the verification of data sanitization it will improve the process of ICT asset disposal.
