I use to do backups for my Win 7 64 bit using the backup and restore for creating system images for a while with no issues.
Since 5 days, when ever I launch system image creation, I get the following error:
"Operation failed due to a device error encountered with either the source or the destination. If the source or destination volume is on a disk, run CHKDSK /R on this source or destination volume
and then retry the operation 0x8078012D"
I have a maintenance contract with Dell, we went through all checkings we can not find any issue with hardware. I used 2 different brand new external hard drives but still getting the same error. I did all what is recommended after googling , ChDSK /R on both phyiscal drives of my laptop C and E,, ran other hard drives tool, all reported that there were no issues with hard drives.
I followed also instructions at the following thread given by Aaron - G, MS system engineer without success as well.
Have you installed any new devices or updated the driver recently? If so, please unplug the new hardware and perform System Restore for a test.
