This is a function that I start manually, when it is convenient, so it doesn't interrupt other functions. I sync different hard drives, across machines and for backup. The contents should be identical. The image is a screen shot of TeraCopy version 2.3. It shows a list of sample files on two hard drives, S and T. I clicked "Verify" at the bottom. As shown, TeraCopy computed and compared the CRCs for the files. In this case, all matched, so the files are confirmed to be identical.
