Ghost and mounted volumes

Should work. I'd just suggest you don't clone directly, but use ghost to create an image file which you can then use to build the new drive. Norton Ghost 2003 should work.

I don´t have enough storage to create an image. I want to clone direct from disk to disk. I've tried with Ghost 7.0 and the -IA switch but the dynamic disk is still dimmed. What shall I do?

Media Tools pro is to expensive... I tried with Symantec Ghost 8.0 instead and now it was possible to choose the dynamic disc. First I tried to do an ordinary copy but when Windows 2003 had started I got some message about corrupt AD and when I tried to log on it logged me off directly. Then I tried to make the copy with the -IA switch. This time I got this message "Not found any active partition in HDD". So I used BootIT NG to make the partition active. Tried to boot again but this time it stopped with a bluescreen. I tought using Ghost would do an exact copy of the original disk but I guess not. Anyone who has a solution to this?

...

Did ghost reboot to legacy mode while creating the image or did it run in GUI mode?

Yeah, Media Tools may be expensive , although with it's datarecovery/data-wiping/hdd imaging and cloning/partition repair options - you know your money is well spent. Did you try to find / searchengine a different software that does the same trick but isn't so expensive?
Another option- do the copy using ghost 8.0 and run repair option on your copied disk off of your Win2003 disk. (not the repair using repair console - the first screen) but the one from the second screen - where it will look for your previous installations.
This way your issues related to the addressing in dynamic partitions should be resolved.
Good luck!
