The build process we are trying to apply is an OEM build process which currently works fine under MDT 2010.
The task sequence and build process involves copying down the Media deployment to a primary partition then applies the WinPE task sequence then once the machine is restarted this should boot into the deployment point to continue the build process. The error below occurs during the OEM phase during the Apply WinPE stage and Prior to the final reboot.
Below is the machine type and exact error message.
We have some HP Z (220,420,620,820) range machines that contain internal Card Readers.
During the stage within our task sequence that applies the WINPE environment we get the following error "Unable to determine destination disk, Drive or partition error 5456".
I have review the .vbs and .wsf files from MDT and found that the error is located within the ZTIUtility.vbs script and we think that this is because the Card Readers are confusing the apply script as they are all allocated driver letters even within the task sequence phase.
We have got around the issue by disabling the Card Readers from within the BIOS and then re-enabling them post build as part of our build process.
I have reviewed the code and I am a little unsure what needs to be changes without causing other issues.
Any help appreciated.
