How can I check that all files on copied partitions are OK?

Question

I've moved my OS and copied another data partition to new SSD with AOMEI Assistant's "Migrate OS to SSD" and "Partition copy" respectively. How can I check that every copied file and partitions in general are OK? Is Windows 8.1 disk check tool enough? It's really important data, even a single damaged file can be a huge problem.

if a single damaged file is a huge problem, you should re-evaluate your backup strategy before you worry about this. Any hard disk/ssd has ~1% chance of failing. — camelccc, Sep 14 '17 at 22:31
@camelccc This is not the only drive I'm copying files to. But I want to know, is there a utility, which can check every file, not only partition in general? — JustLogin, Sep 14 '17 at 22:39

If you really want to check every single file, here's a way to accomplish it with Powershell:

Get-FileHash -Algorithm MD5 -Path (Get-ChildItem "C\*.*" -Recurse) | Export-Csv \\someplace\hashes.csv

This will generate a CSV file that lists every file in drive C, along with hashes. Run it on both drives and compare the hashes. However, a typical Windows installation has many thousands of files, and this could take a serious amount of time. Consider narrowing the operation down to only files that you really care about.
