The /diskwipe switch wipes the entire disk, partitions, partition table, MBR, and
all used and unused space.

Depending on the version of GDisk that you require, the syntax for the delete
command is one of the following:
gdisk disk /del {/pri[:nth]|/ext[:nth]|/log:nth|
/p:partn-no|/all}
[/qwipe|/dodwipe|/customwipe:n][/[-]hpa]
