Hi Don:

A single hard drive definitely won't last longer. We've discussed managed/migrated storage ad 
nauseum here. Don't worry, I think you're probably older than I am, so your CDs will outlast you if 
you take care of them. I'm guessing mine will too, but I've already had problems with seldom-played 
early-era discs. One problem CDs have is that they warp even under good storage conditions. I assume 
the plastic expands and contracts and a different rate from the aluminum, perhaps causing warping 
over time. Once they get un-flat enough, they are hard for many players to reliably read at 1x 
speed, but seem to be OK to rip in my Plextor PC drive.
