Diesunddas

For ZCM prior to 11.2.3a: If the data in sectors 6-63 is not required, then to clear the space (after taking a backup, see Additional Information section below), at the bash prompt issue the following command:
dd if=/dev/zero of=/dev/hda bs=512 seek=5 count=58
N.B. for SCSI or SATA, use:
dd if=/dev/zero of=/dev/sda bs=512 seek=5 count=58
Be very careful to get the syntax correct when issuing "dd" commands on disks that contain data, as using the wrong parameter may erase all of the data on the disk.
