In my work as a freelance computer tech, I've had to deal with a lot of fried hard disks of data, including digital snaps, that weren't backed up, and are not coming back (unless the client pops for sending the HD to DriveSavers or the like for a "CSI"-style forensic recovery job...and you don't want to know what the tab for that can come to).
I've also had some "name-brand" CD-Rs flame-out on me after three years or so, even when stored in darkness (never, ever, leave a recodrable CD/DVD exposed to sunlight for any extended period). I've now standardized on Verbatim DataLifePlus CD/DVD media for this very reason: short of blowing lots of cash for gold-media CD/DVDs, these help cut my potential losses.
Redundant storage (multiple HDs) is certainly better than nothing, but when we're in an age where we're talking terabytes, not even gigabytes any more, things can get unweildy awfully fast:
Little boxes
On my workdesk
Little boxes
Filled with terabytes
Little boxes, techy boxes
Wired boxes, in a row
There's a Maxtor, and a Quantum
And a bunch of Western Digitials
And they're al filled up with terabytes
And I pray one doesn't blow
(With apologies to Malvina Reynolds)
And, yes, perhaps the planet gets hammered by a decent-sized asteroid some time off in the future and all of this becomes moot. But I'd still like my images to hang around a bit, whether anyone's interested in them or not.
Film ain't perfect in this regard, either, of course, but it's easier for me to keep under wraps, so it remains my principal medium, both for work and personal stuff.
Whatever your views on film vs. digital, trust me on the CD/DVD issue.
