I've been using True Image 8 for some months now, running an automatic back-up every morning without problems. The other day I got the following message: "E000101F4: Failed to read Data from Disk" followed by a sector number. I clicked on "retry" without success, so then clicked on "ignore" and the run continued a little while, before stopping with the same message at another sector. Clicking "ignore" again allowed the back-up to complete. I've cleaned up the relevant partition with everything I can think of, including defrag and chkdsk, but each time I run a back-up the same thing happens at the same sectors. Any suggestions how to cure this?
