Usually HDDs come with GPT file format and a normal disk wipe will often not work. Not sure what the SMP process and/or tool is to wipe the disk, but i found the best and only reliable way is to use Diskpart to clean the drive. Maybe that is the cause for the issue you find?
What do you refer to when stating x86 or x64 environment - WinPE automation i assume?
PS: Is this now resolved for you?
