Clone in VMWare seems to of frooze

Hi,

I'm cloning a virtual server in vmware from one host to another. The VM machine has 2 disks; 30gig and 1TB.  The 1TB disk has 300 Gb of data.
The hosts are running ESX 3.5 and I'm using the Infrastructure client for the process.
The status was at 1% for about 20 minutes then is shot to 94% and it has been like that for the past 2 hours. I'm worried that it may be stuck.
The 2 hosts are on a vlan and have a 1gig Ethernet connection to each other.

I have perceived that it will take 3- 4 hours for the clone to take place. Would this be the case?

I have also tried doing an SSH to the host to check the size of the vmdk files but due to an unknown root password I have not been able to do this. By using the Browser utility in the VMWare Infrastructure client I can see that new machine disks are there and the disk sizes are correct as well. But to transfer over 1TB in twenty minutes?!

I don’t want to cancel it as it may be working away....?
I have no other way to check for activity etc, can anyone advise?

Many thanks in advance.
