Aligning Windows XP VMs

Hi All,

I have to align 425 vmdks from 425 desktops. Nowdays, it is 3x ESXi 4.1 HA Clusters.

I wanna create a very simple program using vSphere APIs to make this task.

Looking for the API, I believe that I need to use VDDK to accomplish this mission. My questions:

0. I know that I need to create a new vmdk, with the same size from the original. After create it, how I make this alignment?

1. With the alignment done, I need to copy all the contents of the original partition(misaligned) to the new vmdk into the new partition aligned. How to do this?

Please, help me, you don need to send me the code, only give a direction .... I appreciate any help!

Thanks,

Nascimento
