Mike, While this will erase the logical track presented to a CKD host, it does not actually erase the data on the physical drive.
You need to use the vendor's secure erase facility if the controller has one, or actually overwrite the whole volume with your favorite data generation or copy utility if you want to erase the contents from the physical disk drive.
