Source and target VMs have different disk configurations

Hi Buddies,

I am a beginner to PlateSpin Protect and I have started experimenting with it since a few days ago. It was noticed that the source VM had only one disk but the target VM had two disks. Can anyone tell me why this is so? The source and target VMs were on different ESX hosts in the same VMware vCenter 4.1. The source VM was running RedHat Linux ES5. PlateSpin Protect 10.1 was installed in a VM in the same host as the source VM.

William.
