This is quite amazing. After 5 months of using the in-built backup facility,
Vista suddenly decides that it is not going to be helpful anymore. Everytime
I attempt a backup I am getting a a 0x80070005 error. This is stupid. I have
over 1Tb of storage available to me so I shouldn't be getting this error. I
have also attempted to backup to another external drive and the same problem.

Easy to solve I thought. I have spent the last 6 days on the Net trying to
find a solution and there isn't one. I have chkdsk the drives, run utility
programes and everything is saying the drives are ok.

MS don't have an answer. Does anyone know what to do?
