Query: fails to back up hard drive

I have used Norton systemmworks to keep my hard drive operating. I backed up my hard drive 3 times with Ghost but when I needed to restore the hard drive, each of the ghost images failed with an error 437. There was no warning that the images might not be able to restore the hard drive and once you begin to restore the image, the hard drive is wiped clean. AVOID THIS PRODUCT. AVOID THE GHOST BACKUPS.
