Environment

Novell ZENworks 11 Configuration Management Imaging
Novell ZENworks 11 Configuration Management Support Pack 1 - ZCM 11 SP1 Imaging
Novell ZENworks 10 Configuration Management with Support Pack 3 - 10.3 Imaging
Novell ZENworks 7.3 Linux Management - ZLM7.3

Situation

Although ZENworks Imaging is supported with SSD (Solid State Drive) and other Advanced Format Drive (AFD) devices (see TID 7008796 "Support for Advanced Format Hard drives with ZENworks Imaging") , there can be a problem with drive alignment when restoring images.

Resolution

Note that the fixes shown below for May, are for Linux devices: the fix for Windows devices was part of the February 2012 update (but of course included in the May update).

When the fixes shown below have been applied, note that to assure alignment when restoring to Advanced Format  and Solid State Drives, use the -A (this must be in upper-case) or --align switch, e.g.,
     img -rp archive.zmg -A
     img -rp archive.zmg --align
this is necessary when restoring Windows XP images: it is recommended for Windows 7 but not mandatory (with one exception: if a drive previously had Windows XP installed, and is "upgraded" to Windows 7, it will still have the old XP partition format, and in this case, the the -A parameter is mandatory).Note that using the GUI interface will not work for this switch, and see TID 7006411 Imaging switch to align harddrive does not work combined with parameter to stretch partition size for details of how to use the -A switch when performing selective restoration.

Do not use this parameter when restoring to non-AFD drives.

For ZCM 10.3.4: This is fixed in the ZENworks Imaging Update for May 2012 - see KB 7002402 "How to obtain the latest ZENworks Imaging Updates" found at https://www.novell.com/support for details of how to obtain this update.

Note that it is partially fixed in the shipping version 10.3.4 - see KB 7008244 "ZENworks Configuration Management 10.3.4 - update information and list of fixes" which can be found at https://www.novell.com/support
With version 10.3.4, images from new Windows 7 devices can be restored directly. Note that the Additional Information section below gives details of a -A parameter: this parameter is not present in 10.3.4, which means that in order to restore XP images, it is necessary to use the tools from the disk manufacturers to ensure that the drive is "aligned" before taking the image.
