Article on data rot on CD's

Just to add my "me too's"...

Buddy of mine has had bad experiences w/ labels. Some brand of CDR
(probably cheap ones) was fine w/ out a label, but as soon as he put his
(also probably cheap) label on it the CDR turned into a frisbee. (Shrug
- I now avoid labels.)

I've also noted that a lot of the cheaper DVD-R media is obviously
semi-transparent, and I'd be concerned about the effects of labeling
one...

But FWIW, I've seen true CDR "bit-rot" only once. Can't remember the
brand or other details, but the one day I went to use this one CDR, all
attempts to read any of the files on it caused CRC errors to start
spewing on in the message log. It'd been sitting on the shelf in a case
for quite some time ( < 7 years, see below ) and there wasn't any
noteable physical damage to the media either. <shrug>

I'd agree its all about the brands though, as it looks like the very
first CDR I made back in 1997 is still quite readable (even though it
_IS_ fairly scratched.)
