I started to archive to CD (too small a capacity) then to DVD (too slow) and
finally I bought a FireWire enclosure with drive trays and some 180 GB drives
from Frys that were on sale at a darn decent price. I keep the drives, in their
trays, in the dark, in an a/c room, in boxes. That SEEMS like about the best I
can do. So far no problems either finding things or accessing them. Forcing
myself to build the data archive for the images thought - THAT'S a problem.

And, of course, I keep the negatives although the TCN ones will certainly fade.

Still, I have confidence that the on-disk file structure will last quite a while
and that I'll have both warnings and alternatives when it does change.

I don't think I've ever seen a spec for hard drives in "storage" mode. Brian?
What do you think? What's the point of failure and how often should I spin up a
drive? Monthly?
