I have read several comments in posts about disabling Win XP's own CD writing software before, and have done this in Drive Properties' and got a good CD which restored an entire partition to my laptopimage. I assume that Acronis found the installed burning software on my machine and used it? Question is 'why cannot I simply use XP's native burning software. P.S. having browsed forums before trying disk backup/restore I was not hopeful about it working first itme, but it all passed with flying colours - congrats acronis!!
