Hello everyone.
I've a lot of people encounter problems similar to this, but here is my particular flavour:
I have a Windows 8.1. Pro (64 bit) desktop PC.
I am trying to use File History > System Image Backup to create a backup image of my C: drive.
I have been trying to save the backup both an external USB 3.0 drive, and this time to a network location (on a WD 'MyCloud' EX4 NAS)
Every time, the backup fails about 3/4 of the way through.
I get an error dialog saying
"The backup failed. The operation failed due to a device error encountered either with the source or the destination. If the source or destination volume is on a disk, run CHKDSK /R on the source or destination volume, and then retry the operation. (0x8078012D)Additional Information: The request could not be performed because of an I/O device error. (0x8007045D)"
I've spent many hours diligently running CHKDSK /R both on my C:\ and the destination drives, and it has never once found any problems.
I've tried closing all applications, unnecessary services, background processes and disabling Windows Defender's real time malware checking whilst the backup takes place, but that doesn't seem to fix anything.
My hunch is that there's nothing wrong with the disks or hardware at all, and that this is some kind of obscure permissions problem, where Windows can't access symbolic links on my C: drive.
But I basically haven't a clue! :)
I'd be very grateful for any suggestions at fixing this, as currently I don't have any backup image of my C:\ drive, so if my PC goes kaputt, I'll have days of manual re-installing and configuring to do.
Thanks.

Yes my C drive is also an SSD I was unable to login to windows one day so I had no choice but to reinstall windows I'm just not able to explain in right words exactly how I fixed it I will record a video and post online If I have the same problem though. I know the steps I took to fix the problem
No - my C drive is an SSD, so should not be defragged.
I appreciate that you're just trying to help,
but telling me that the solution to me not being able to back up my OS is that I reinstall my OS from scratch is a bit silly!!! :)
If I am going to reinstall my OS from scratch every time I have a problem, there's not much point me taking a system image of it, is there? lol
Don't know if it will work for you but worked for me. Ran disk optimization on my hard drive even though analysis says it wasn't necessary and then ran system image backup. Success!

I have fixed this error on my system running windows 8.1 I had windows 7 8 then upgraded to 8.1 via windows update the issue I was having was the data stored on the drives leftover as I updated to the next OS I deleted everything except the efi bios even the system reserved MSR information stored on my hard drives and that seemed to fix the issue for me. Then fresh installed 8.1
