Just a small note. I think you're confusing things here.
MD5 shouldn't be used for password hashing because it's unsalted and vulnerable to collision attacks. But it's still fine to use it for basic file integrity checks.
Being less computationally expensive than other algorithms such as SHA512 also makes it easier to crack (when used in a cryptographic system). And this is precisely the same reason it's more interesting for basic file integrity checks compared to the rest. You'll notice the difference when you want to generate checksums for thousands of files.
wow, wasnt expecting this, im getting all different checksum values
i think i will extract the tar and cross reference it with the source directory ie do on both
count number of files
size of directory
SHA512 (/vol/cha-work/_ARCHIVE/to_be_archived/audio/chad_r/2017-05-17/Even When I Fall - January 2017 Project.tar) = fa8a0c210f4616f27de9e66d5316bce62881baf794214ebecbf4a6fd576e09b274b278f0bef278315e12159083073975f02e5f03aff18682e5273722287df799
