Chapter 13. Disk sanitization
This chapter describes disk sanitization and the process of physically removing data from a
disk. This process involves overwriting patterns on the disk in a manner that precludes the

confidentiality, technology drivers, costs and risks, and the sanitizing operation.
This chapter includes the following sections:
򐂰 Data ONTAP disk sanitization
򐂰 Data confidentiality
򐂰 Data ONTAP sanitization operation
