i have a small update on my original email (i haven't had a chance to try
the items below).

When I run Ghost, the CD drive is listed twice, once via it's drive letter
and once via it's ATAPI direct access.

Access via drive letter fails repeatably.
Access directly works.

I don't know if that sheds any light on things.

I will try the other suggestions tomorrow.

Thanks for your valuable help.

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing 
also focuses on allowing computing to be delivered as a service.
