at issue is the formatting of the drive itself, the format of the files
themselves, and the integrity of the hard drive mechanics and electronics.
following the lead of biggest businesses/banks in the world, and how
they archive their data, seems prudent. they don't need data for just 7

you're Ken of Enron).
a combination of hard drives and AIT or LTO tape is the gist of the
documents listed below.
if you've time, please see this PDF file for details concerning
archiving, put together by the record industry, which has a very big
investment to protect. This is from the Producers & Engineers Wing of
NARAS and the Grammys.
