Here is a link that might further explain....

Norton Ghost 9 is (was) based on a product called "Drive Image" from
PowerQuest. Symantec bought PowerQuest because it was easier to buy the
competition which, in my opinion had better products, then to impove what it
had. That being said, PowerQuest products were always VERY picky about the
state of the drive. Practically ANY error at all would cause the program to
fail. Sometimes these errors were reported pretty much from the get-go but
others would occur only after you had spent a considerable time executing
the program. Bottom line is that this error probably is an indication of a
disk error of some kind and running a chkdsk before attempting another
backup would probably take care of your problem.
Just an FYI though, If you pick up the latest issue of PC World there is an
article in there about a similar product called True Image from Acronis
Software
www.acronis.com which beats out Ghost 10 in functionality. I use
the product and swear by it and with Acronis you will get first rate
personal attention to your concerns.
Even if you switch, I would still run a chkdsk on your system before trying
another backup.
Regards.
