I've had CD's "go bad" while I was writing them, if that's what you
mean. I don't think the writers are the problem. The CDs themselves are.

Yes, I plan on it. Then when they don't, I'm all the happier. But they
do sometimes go.

I'm not sure you're interpreting those specs correctly, and I also think
you're talking about SCSI drives, which indeed are built to last moreso
than IDE drives, although I really don't get the point of a drive
lasting 10 or more years when in ten years it would long be replaced
anyhow because of Moore's Law applied to disks.

Yeah, and they're so cheap, who cares if they go bad in a couple years?
I want to update my drives every two years anyhow because of the rapid
increase in capacity.

Yeah, I have some 2 gig Seagates lying around that will probably never
go bad. They're sitting in a pile somewhere and will never ever be used
again.

Wonderful. Keep your expensive high end drives for 10 years. Meanwhile
everyone else will be using el cheapo drives with 1,000 times more
capacity.
