Drives
Hard drives and solid state drives are often used to store sensitive information. To protect this information from unauthorized disclosure, sanitize drives prior to reusing, decommissioning, or disposing them.
-
Use disk-wiping tools, such as the format command, to completely erase all data from the drive. For more information, refer to the Oracle Solaris format(1M) man page.
-
Organizations should refer to their data protection policies to determine the most appropriate method to sanitize hard drives.
-
If required, take advantage of Oracle's Customer Data and Device Retention Service. For more information, refer to this document: http://www.oracle.com/us/support/library/data-retention-ds-405152.pdf
 | Caution - Disk-wiping software might not be able to delete some data on modern drives, due to the way that they manage data access. |
