Just wanted highlight the edit. Thanks
I found this thread which seems to describe the same problem that I have. What do you guys think?
Edit: It would have helped if I had included the link!
Windows 7 prof 64 bit Backup Hang after 75% done (0x80070003)
Anyway, chkdsk found no errors. And sfc /scannow found no errors. And, a utility cd that came with my PC had a Western Digital disk diagnostic, SMART, that found no errors. So, all diagnostic efforts have found no errors more than the original replaced clusters in six files, yet image creation still fails. Maybe the HD is failing, but if so why no way to confirm? I still wonder if a corrupt file is causing the problem? And why can't some diagnostic find the corrupt file?
Thanks for any additional advice, Jim
