Hello!

I encountered unexpected errors when I tried to incrementally backup my photos. I used Cobian 11 software and I copied from one WD hdd to another identical drive.

I can view files on both drives with no problem, also chkdsk doesn't show any problems.

That's the type of error I encountered using Cobian backup 11:

What is the problem and how to fix it?

I checked some of the files that are supposed to be missing and I was able to view them in Explorer.

User on this computer has all the premissions for both drives.
