What does this error tell me?

one of my clients does not do a image backup because of this error message:

Error on client occurred: Error while reading from shadow copy device. Datenfehler (CRC-Prüfung)

last translated Data error (CRC Check)

Does this mean my Harddisk on the Client is nearly dead? Or is there some Software blocking reading from shadow copy device?

Did it work/fix the problem?

it seems to be the harddrive, have to play back an older image with trueimage because urbackup was not able to do a image backup because of harddrive problem.

Is there a way to force image creation regardless? Maybe have that part be all zeros or something? So that at least the rest of it is saved?
