ZENworks Full Disk Encryption encrypts data. As with any encryption product, you should image target devices prior to performing encryption. With ZENworks Full Disk Encryption, this means that you should image a device before assigning a Disk Encryption policy to it. If encryption or pre-boot authentication fails on a device, you can apply the image to restore the device.
For information about using ZENworks Configuration Management to image devices, see the ZENworks 11 SP4 Preboot Services and Imaging Reference.
