Windows 7 backup, error message 0x80070002

My client's Windows 7 32 bit computer won't back up to a 1TB external hard drive. I'm getting error message 0x80070002.

When I look at the drive, I see three items: [user name-PC], which has a folder within called Backup Set 2013-11-06, but it is empty. I also see a folder WindowsImageBackup, but it is also empty. The third item is MediaID.bin.

The system seems to go through the backup process but then I get the error message.

Last week I thought it might be the drive, so I've installed a new external drive (1TB), but same problem. Don't know what to do other than buy a third party solution.

As you get the error and go to EventLog Viewer do you see there the errors?

or if you think an NVidia chipset could be the problem, Scenario 3

Thanks. Solved this for now...am waiting the next scheduled backup though. All comments above are relevant and topical; "empty" folders are explained by the protected OS files settings; never did find error messages, but did this: reformatted the drive and started over. Thank you to all.
becorson--You are welcome.

Next time you are thinking of a reformat consider a Repair Install instead

This does not affect personal data or installed programs.
jcimarron--Whoa, thank you, but the reformat I did was on the backup drive, not the system drive. Sorry for the confusion. I did like the instructions though. Thanks.
