It cannot be *totally* unrelated. A manufacturer doesn't want a whole
lot of returns. You can expect that *most* drives will *at least*
make it through the warranty period.
A hard drive is free to continue operation well past the warranty
expiration time. As far as I can tell, the 3 to 1 year standard ATA
warrenty shorting has had no impact on actual drive lifetimes.

Actually, i'd prefer if they'd just implant a large storage system in his
rectal passage, but seeing him get blown up by a tomahawk missile could be
fun, too

Indeed they can - I have a Lian Li case which, so far, appears upto the job.
I was looking at getting CD bay drive coolers for any 15k drives I get..
Thanks for your advice

Yes, just as you "always said" there was nothing wrong with the Deskstar

Oooh, those were almost as nice as the 36LZX 18gig ultrastars. I had 50
servers delivered, each with one of those drives. I had about 60 exchanges
on them before my vendor started giving me seagates

HP Surestore 2000. Six drives, ten failures, we finally gave up when we
called HP for a replacement and got routed to some noname 'support'
organization. Apperently they'd sold the whole drive business, lock, stock,
and warranty.

Such claim would be wrong...
As with any product the percentage of failures will
increase over time; e.g. .5 % during first, 1 % du-
ring second and 2 % during third year of life.
Thus increasing the warranty time does indeed cost
money...
Manufactures will work hard to get the failure rate
as much down as possible (less cost, competitive
advantage).

Nonsense. It's the opposite for the first three years: over 1% in first year,
under 1% in next two.

Assuming you're right, after how many years the failure
rate would have come down to 0 % then?
Believe me, the rate goes up ... (until no drive will
work anymore, i.e. 100 % failures; just wait - may
take a few years, but it will go there

It's usually taken for granted that the failure rate is plotted as a
"bathtub" curve. Here's an attempt at ASCII - view with a monospaced
font:

time
^ ^ ^ ^
1 2 3 4
The x-axis is time, the y-axis is failure rate.
What this says is that drive failure is high in their infancy (between
points 1 and 2). If they see out infancy, they tend to continue working
(between points 2 and 3) until they reach some point at which they wear
out, then failure rates increase (between points 3 and 4.)
Traditionally, the gap between points 2 and 3 has been three years for
consumer-level (=IDE) drives, and five years for high-end (=SCSI)
drives, coinciding with the typical warranty period offered on these
devices. Of course, this is generalising wildly and depends very much
on how the drive is treated prior to installation, its operating
conditions, etc. etc.

....which means the 'curve' is upside down, but I can guess what you
intended: reliability = 1/failure rate ???

Common phenomenon with electronics of any kind--a high rate of "infant
mortality" in the first few months of operation, then a relatively low
failure rate until pieces start dying of old age.

Same thing i've seen in most drives. Once you weed out the badly
manufactured ones, you'll see little or no failures. After several years of
non-stop operation, turning them off will make a buttload of them die at
once, though.
