Backup failing with error "Failed to read data from the disk" and "Failed to read the snapshot"

Thread needs solution

A few days ago a Windows 10 upgrade corrupted the OS and my PC was unbootable.

I successfully restored my computer with Acronis 2016 Rescue Media.  However, since then, when I do a backup, the backup keeps stopping with the error (attached). I upgraded to Acronis True Image 2018 hoping the problem would be resolved and so I could open a ticket if it wasn't resolved.  It wasn't resolved.  Then I ran the Repair function, and did the backup again. Still the error.  Chkdsk /f /r ran successfully, so I don't think the hard drive has a problem.

I see a lot of posts on this problem on the forum for past versions, and I've done the easier things that have been suggested. But I hesitate to start fiddling with the registry regarding VSS settings.

I did open a ticket and am awaiting a response.

The backups are validating, so I think (hope) they are usable (are they?).  But I can't run them unattended unless I can suppress the error message which tells me the backup requires user interaction, not that I like that approach.  I would like to fix the underlying problem.

Any ideas?

Anita, welcome to these User Forums.

The error message you are seeing is an indication of a disk drive error, probably a bad sector, but it could be located in an area that your current CHKDSK cannot access, i.e. on a hidden/system partition on your main OS drive.

The reference to snapshot / VSS would suggest that this type of data is being stored in free space in the same area of the drive.

There are several approaches that you can take with this issue.

Try making a disk & partition backup of each individual partition on your disk drive, and do this one by one in separate tasks.  This should help establish which partition this error is being generated for.

Download and run the free Acronis VSS Doctor tool (link in my signature) and let this check your VSS configuration and allocation in a safe way.  If the tool finds any issues, then take the option to repair the same if offered.

Identify the maker of your disk drive and visit their support site to download any whole disk diagnostic tools that they provide, then check the whole drive using this.

Dedicated diagnostic utilities from the disk manufacturers take the longest time to complete the checks, but provide the most accurate methods of checking whether the disk is good or needs replacement:
