For more confidence, do what I do: use a checksumming utility to create hashes of all the files on the drive and then verify them from time to time to make sure the drive hasn't corrupted any data.

Ok. The "checksumming utility" sounds interesting, is it some outer program that you place on every separate HD, or place on the C: drive or is it something already available on Win 10 pro or...

Google "checksum utility".  You put this program onto your system and run it to scan all the files you want to protect - it will produce a "checksum file" containing the hash values of all the files you scanned.   Then at a later date you run it again to rescan the files and ensure that their checksums still match the ones in the "checksum file".
