trying to clone failing drive, Ghost 15 hangs at 99%

I am getting warning messages from Windows that my S.M.A.R.T. drive is about to fail. I am trying to copy the disk to an external hard drive with Ghost 15, then will try to recover the image to a new hard drive.

 

Ghost is hanging at 99%, and I can't complete the copy part of the operation...

 

Any suggestions?
