Erasing a Disk

Deployment Solution

You can use the Erase Disk task to wipe a disk clean. Hence, the partitions along with data are removed from the client computer. When you reallocate hardware, you can use this task to ensure that none of the old data can be retrieved. You can either delete the partitions of the disk, erase the system disk, or configure the task to erase all the disks. You cannot perform an Erase Disk task for a disk that is connected through a USB or FireWire interface.

You access the Erase Disk task from Manage > Jobs and Tasks menu. In the Jobs and Tasks window, expand System Jobs and Tasks and right-click Deployment and Migration > New > Task option. In the Create New Task dialog box, access Deployment and Migration > Erase Disk.
