TeraCopy can automatically check/verify the copied files for errors, by calculating their CRC or other checksum/hash value.

TeraCopy skips badly copied files during the copying process, and then displays them at the end of the transfer "Verify" with checksum/hash, so you can see which files to re-copy. See also, OpenHashTab for Windows and DeadHash for Windows, Linux, Android.
Cons
Con Sometimes clashes with 7 zip
From my experience, TeraCopy does not do well in conjunction with 7zips.
It seems to error on some systems when you do a drag-and-drop extract.
