I think most of the times it's not 100% the HDD manufacturer.. I uses to
repair HDDs and powersupplies and everything else you can thing of and one
major thing I noticed is that the power supplies are underated. I have seen
so many people buy these cheapo cases which have powersupplies marked at
300W but were lucky to get a constant 250W.
Yeah, that's robbery but it does happen and when the drives want more grunt
and on power up pull heaps from the power supply I have seen noise come from
some of them too.
So it also also comes down to good power supplies and people fitting them.
I personally don't like Seagates and fujitsu drives but some other people
probably do.. just my non preference...

We recently upgraded several of our serverds. We had a total of 4 HDD
failures
on reboots, including 2 failures from a RAID 5 array (luckily in that case
we we
shutting it down prior to formatting the whole thing, so the data loss
wasn't an
issue- and the other systems used RAID 1 so we could just rebuild the
drives)
I've only ever seen this on unix/linux systems - windows reboots so often it
causes the failures to be detected much sooner. Unfortunately rebooting the
systems regularly to check for faulty hardware isn't really an option with a
live network. How many other people have seen systems that have been
working
fine for a very long period of time fail when reboot? And how many people
have
lost a redundent RAID array to multiple HDD failure?
I should also mention that my old Quantum Bigfoot drive also gave up around
the
same time - so maybe it's just all bad luck on my part.
