Sanitizing a Drive
You can erase the data residing on a drive using the Sanitize feature. The Sanitize option is similar to the Drive Erase feature that is already supported by your controller. The difference is that the Sanitize option is performed by the drive firmware, whereas the Drive Erase feature is performed by the controller firmware.
The Sanitize option is an industry standard SCSI feature and uses an industry standard Sanitize SCSI Block command. The Sanitize operation is constantly monitored the by controller firmware. Drive sanitization progress events are communicated through the Background Operations Support feature.
