    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) = fa8a0c210f4616f27de9e66d5316bce62881baf794214ebecb f4a6fd576e09b274b278f0bef278315e12159083073975f02e 5f03aff18682e5273722287df799

    find -s /vol/cha-work/_ARCHIVE/to_be_archived/audio/chad_r/2017-05-17/Even\ When\ I\ Fall\ -\ January\ 2017\ Project/ -type f -exec sha512 {} \; | sha512
