Right the network driver was updated.
I did not follow did he apply the updates and reboot? Or did the updates get applied and the reboot was pending, which he then did? -

Updates were applied and reboot was pending on the network driver. Starting to think this was the issue, even though I don't understand how or why it would have caused it.

Network driver... copying files across a network.. Nope cannot see it..
Or did I misunderstand the copy process? Was it all local?

@jaredbusch From one folder on the share to another folder on the share from a client computer. Was reproducible on specific directories before restart. Copying same files down to a networked computer locally - then back up to the share resulted in legitimate copy.

That's a definitely likely situation. Drivers getting updated but not reloaded means that what is on the disk and what is in RAM do not match and there might be an attempt to load something from disk later and get a conflict.

Yup, that's network. So the network driver was definitely in use during the process. So while we are just guessing, it's a very rational place to start to guess at placing blame.

@scottalanmiller Really appreciate the input. Didn't know if it was possible for chkdsk to not pick up corruption issues or it was something mid flight. Intel drivers seems to make the most sense.

Chkdsk can pick up certain types of file corruption, which you did not have. You had a network issue, which is completely different. At no time was any file corrupted. The original file stayed pristine. The new file was written flawlessly. Neither file was corrupt.

It WAS mid-flight. That's known. What is a guess is that the driver is at fault. But I'd say that it is pretty likely.
