Then you haven't bothered to check the dead parts bins at many
computer shops. Optical drives die all the time, or just read so
poorly that they're not reliable... same thing.

That doesn't mean they died because of excessive usage. The optics get dirty
in dirty environments, not because of usage.


It is a good theory, but I've opened a few, and many weren't
particularly dirty inside, in fact I was surprised at how clean some
were. If you're suggesting a laboratory cleanroom, there's an idea,
but many drives that fail do not appear to be victims of dirt. I must
admit I didnt' do a complete autopsy for a cheap optical drive(s) so
the actual cause of death in most cases would be "unknown" but dirt
didn't look to be the problem.


Loading your system up with redundant CD/DVD drives does risk spin-up
power
sags, which can cause bad sectors on your hard drives.

Nonsense. If that happens the problem wasn't an optical drive, it was
an inadquate power supply. I'm not so sure HDDs will even suffer bad
sectors these days, generally it takes a HUGE voltage sage to be
significant, not an amp or two.

Poor power and cabling is the leading cause of bad sectors. It is a major
problem.

This has been acknowledged in every storage forum.

But that's not the same as adding an optical drive, two distinctly
different things. Poor power is the cause, not the optical drive, and
if adding one reduces the voltage THAT much there was ultimately going
to be a problem regardless.

I will grant you that if a system was using the entire capacity of the
power supply already, it wouldn't be wise to add an optical drive (or
anthing else), though it wouldn't be prudent to operate the system
like that for any length of time anyway.

One last question, can anyone please explain this:
