Hello Matt - 

CA>> What I've been reading lately tells me that even burning
CA>> image copies to CDs is not foolproof indefinitely. I don't
CA>> see as much effort being put into securing copies beyond a
CA>> few years and that worries me. Data can be useful for more
CA>> than a few years and my source code is valuable (to me) as
CA>> a reference if nothing else. 

MM> Saturday I was cutting up some 'replacement CD washers' 

Refresh my memory again - what are these 'washers' used for? 

MM> and was thinking of my previous discussion on CDs in the
MM> sunlight, and how brittle and flaky the ones I was
MM> presently trying to cut were. It was almost like trying to
MM> cut 'Plexiglas' with a hatchet, they just crazed and
MM> cracked randomly every which way. I had a few DVDs in the
MM> pile and tried cutting those instead. To my suprise, they
MM> separated easily into two extremely flexible layers of
MM> about equal thickness. My _guess_ is that the data layer
MM> was in the center, but there was nothing as obvious as the
MM> CD data layer. ???? 

I don't know the answer to that. 

MM> Just yesterday I got a commercial Ad., thought about this
MM> conversation, and captured part of the ad: 

MM> MM> ----- 100YEAR.TXT begins ----- Prodisc 2X 4.7 GB Silver DVD-R
MM> MM> Media, NO Stack Ring!
MM> 
MM> 
MM> --8<--cut
MM> 
MM> MM> ----- 100YEAR.TXT ends -----

MM> If the CD people aren't think about "long term", at least
MM> the DVD people seem to be! 

MM> Just for whatever it's worth! 

I would like to believe them but this "100 years" thing was
touted for CDs at one time until enough years passed that
people began to experience the reality that it was all
smoke-n-mirrors. 

I will need time to pass and to see that DVDs aren't
corrupting. At this time I do not trust any of the so-called
'labs' out there that do testing of computers or related
equipment or media. They ALL lied about CDs (and many other
things too). :-\
