Norton Ghost 15 has stopped backing up

Hi there, hope you can help:

My (Ghost 15) Backup has stopped working.

 

The error message I get (after about 2 hours of it trying to backup) is:

 

-Unable to read from file.

--Error EBAB03F1: Data error (cyclic redundancy check)

(UMI:V-0-2--1-30)

 

I have been running backups with Ghost 15 for last 6 months and no problems and no changes to my system. Have ran a scandisk and repair and then a defrag, but to no avail.

My OS is Windows Professional

 

Any advice appreciated, Thxs Ray
