+The

+The

+.It Fl a Ar operation
+Specify the sanitize operation to perform.
+.Bl -tag -width 16n
+.It overwrite
+Perform an overwrite operation by writing a user supplied
+data pattern to the device one or more times.
+The pattern is given by the
+.Fl P
+argument.
+The number of times is given by the
+.Fl c
+argument.
+.It block
+Perform a block erase operation.
+All the device's blocks are set to a vendor defined
+value, typically zero.
+.It crypto
+Perform a cryptographic erase operation.
+The encryption keys are changed to prevent the decryption
+of the data.
+.It exitfailure
+Exits a previously failed sanitize operation.
+A failed sanitize operation can only be exited if it was
+run in the unrestricted completion mode, as provided by the
+.Fl U
+argument.
+.El
+.It Fl c Ar passes
+The number of passes when performing an
+.Sq overwrite
+operation.
+Valid values are between 1 and 31. The default is 1.
+.It Fl I
+When performing an
+.Sq overwrite
+operation, the pattern is inverted between consecutive passes.
+.It Fl P Ar pattern
+Path to the file containing the pattern to use when
+performing an
+.Sq overwrite
+operation.
+The pattern is repeated as needed to fill each block.
+.It Fl q
+Be quiet, do not print any status messages.
+This option will not disable
+the questions, however.
+To disable questions, use the
+.Fl y
+argument, below.
+.It Fl U
+Perform the sanitize in the unrestricted completion mode.
+If the operation fails, it can later be exited with the
+.Sq exitfailure
+operation.
+.It Fl r
+Run in
+.Dq report only
+mode.
+This will report status on a sanitize that is already running on the drive.
+.It Fl w
+Issue a non-immediate sanitize command.
+By default,
+.Nm
+issues the SANITIZE command with the immediate bit set.
+This tells the
+device to immediately return the sanitize command, before
+the sanitize has actually completed.
+Then,
+.Nm
+gathers
+.Tn SCSI
+sense information from the device every second to determine how far along
+in the sanitize process it is.
+If the
+.Fl w
+argument is specified,
+.Nm
+will issue a non-immediate sanitize command, and will be unable to print any
+information to let the user know what percentage of the disk has been
+sanitized.
+.It Fl y
+Do not ask any questions.
+By default,
+.Nm
+will ask the user if he/she really wants to sanitize the disk in question,
+and also if the default sanitize command timeout is acceptable.
+The user
+will not be asked about the timeout if a timeout is specified on the
+command line.
