I believe that you should not have to specify 32 or 64 bit while you are taking the Image. The image that you are taking is already using a 64 bit or 32 bit version of rdeploy and should just redistribute that exact same image.

The switch does not work. Altiris support knows nothing about it.

One solution is for you to create an image aligned at 1024KB (which is divisible by 64 and should allow you to achieve the performance increase you expect). DS retains the offset with no issues.

I created a WinPE boot disk and created a partition using diskpart aligned at 1024KB. After this I reboot the computer and install the OS on the drive I just created. That's pretty much it. Once you capture and deploy the image, you will notice the partition rdeploy creates is aligned at 1024kb.
