Imaging 2008 Windows Server Takes 50 hours

I am using Ghost boot disk ver. 11.5.1 to take an image of 5 different Windows 2008 servers. 4 Server's took about 2 hours to create an image (all good) but my 5th server for some reason say's it going to take about 50 hours. There is no more information on the drives than my other servers. Not sure what is holding it up. Advice on what to check or do?
