Morien still hasn't substantiated this claim by any means
other than personal attack and introduction of a discussion
of hard drives and CPU fans, not facts about CD burners.

There is a naive misconception as to what MTBF means.

True, but Morein so far you haven't made the issue
relevant here.

It's a good thing businesses are run-out of the front
office and not out of engineering. Your quoted
statistical models have little practical value in the
real world. Hard drives are spec build based on
managerial accounting (cost/profit). As one Western
Digital representative put it, our drives have a ½ of
1% failure rate. There is no economic advantage in
producing higher quality in a highly competitive
marketplace. So you can lump-in all your stats and
it still comes out the same number (½ of 1% failure
rate).

That would be ½ of 1% per what time period?

IME it might be ½ of 1% per month, or something like that.

Its a quality number, DOAs. Drives that fail the initial format
attempt.
