I have 2 copies of the same data in separate HDDs. Which copy should I use to create the 3rd one?
Otherwise check out Hashdeep: https://github.com/jessek/hashdeep/

I use hashdeep. You have to install ipkgui on Synology and then md5deep through that which includes hashdeep (or just use md5deep). You can read up on hashdeep/md5deep here in the docs folder: https://github.com/jessek/hashdeep/

How do I manage years of data?
Started to be able to bring some order after I discovered hashdeep. Basically I started from a reasonably clean disk with folders to sort files, created lists of hashes using hashdeep, then used it to scan all my existing disks for unknown files. With the correct flags hashdeep can list all files it finds on a disk that it has not in its lists already. That help a lot to figure out what is worth wasting time on. It also is useful because every now and then that makes me realize the copy of some old file I have is broken (probably usually because it was stored on some CDROM that was no longer good).

How do you protect yourself from failing drives and data corruption?
Calculate their digests with rhash or similar utilities (but not too frequently, or you'll beat up your hard drives! once a month is plenty).

External drives content index solution
Yeah, I ran across two programs that did this: https://github.com/rdiez/Tools/tree/master/RDChecksum Uses file existence, file size, and modified date to add/remove/rehash a file in the list. https://github.com/rhash/RHash Uses only file existence So both of these store relative file path/name with the hash to see if a given file is new/deleted, and RDChecksum additionally will rehash existing files if they've been modified. Personally I feel like just the existence of the file would be enough if you could also tell it to rehash just as specific sub-directory from a larger checksum file that you know has been updated

went back to watch an old video, just to find out it was corrupted midway. previous backup must have overwritten it...is there any program that can scan for corrupted movie files or means to compare before overwriting?
checkout rhash

Crypto Resources
RHash is a great place to start. Easy-to-read cryptographic hash functions. Libsodium is your go-to though for cryptographically secure hash and encryption functions.
What are some alternatives?
When comparing hashdeep and RHash you can also consider the following projects:
AntiDupl - A program to search similar and defect pictures on the disk
gtkhash - A cross-platform desktop utility for computing message digests or checksums
snapraid - A backup program for disk arrays. It stores parity information of your data and it recovers from up to six disk failures
libsodium - A modern, portable, easy to use crypto library.
cshatag - Detect silent data corruption under Linux using sha256 stored in extended attributes
tcl - The Tcl Core. (Mirror of core.tcl-lang.org)
k4dirstat - K4DirStat (KDE Directory Statistics) is a small utility program that sums up disk usage for directory trees, very much like the Unix 'du' command. It displays the disk space used up by a directory tree, both numerically and graphically (copied from the Debian package description).
OpenSSL - TLS/SSL and crypto library
Tools - Assorted collection of shell scripts etc. to help with common IT tasks
