That's the trouble with hard drives. Most of us base our opinions on our own
limited experience, and a few bad ones can colour our views for ever...
Seagate acquired Maxtor a year or so ago, and before that Maxtor acquired
Quantum. So the whole hard drive industry is rather inbred, and I have my
doubts that there are significant differences in reliability between brands,
except where there is a major design flaw in a particular model, as happens
from time to time.

Personally, I've yet to have a Maxtor fail, whereas the last hard drive I
replaced because it was faulty was a Seagate, oddly enough! Of course, the
fact that I've just rebuilt a PC for someone using a Maxtor drive makes me
want them to be reliable! The curious thing is, I initially installed a
Samsung drive, only to have it die completely during the install (click,
click, click). I got an identical replacement and tested it using Samsung's
software, and that yielded countless DRQ timeouts on two different
motherboards using two different SATA cables. I returned it and swapped it
for a Maxtor, which passed all the tests without error!

There is a postscript to this sorry tale. I got a phone call to say that the
PC wouldn't boot ("Insert proper boot media"). I decided to bring it home to
look at it more closely. Of course, it booted perfectly. I used the PC at
various times over the next few days, stress testing it thoroughly each
time, and eventually the problem recurred. I determined that the cause was
the SATA cable. Thermal stress and vibrations from the hard drive were
causing it to slowly back out of the socket. This never manifested as data
loss in a running system (though it might have done so eventually), but
always as failure of the BIOS to detect the drive when the PC was rebooted
after cooling down. Replacing it with a latching SATA connector seems to
have solved the problem.

I'm now wondering if the dodgy SATA cable somehow killed the Samsung drives,
though this does seem implausible... But two faulty drives in succession
seems equally implausible!

Have had three failed Maxtor drives replaced under warranty in the
last four years, out of five purchased. Also had a poor record with
Fujitsu drives before that. Have decided for blood pressure reasons
to just try a different manufacturer each time I buy a new one, at
least with no brand allegiance it'll be more random if one fails.

Saying that, I've never lost all the data with (P)ATA drives, having
a spare power supply to power the drive separately to the rest of
the PC has always given me the chance to copy all the data off
before returning the faulty drive.

Then why not add a 50p fan to prevent it failing?

If you know its running too hot then its your own fault it fails

Quite right too! The main problem is that most cases make little or no
provision for cooling airflow around the "Hard drive Bays"[1]. This was
ok when IDE drives ran at 3600 and 5400 rpm and only dissipated some 3
to 6 watts when idle and having more than a single hard drive was
considered a luxury.

Now that today's entry level drives spin at 7,200 rpm and dissipate 8
watts and above, those same traditional case designs are seriously
compromising drive reliability, especially if _both_ "drive bays" are
occupied. In the case of Maxtors, this effect is aggravated by their
even higher cooling demands despite their operating temperaturel upper
limit being 5 degrees higher than the competition.

I suspect that, given suitable cooling, the Maxtors may turn out to be
no more _unreliable_ [2] than any of the other brands. Don't get me
wrong, I'm not endorsing Maxtor, just pointing out why they seem to fall
victim to failure more frequently than other brands.

[1] Proper hard drive bays would be designed to keep their 'precious
cargo' nice and cool. The so called "hard drive bay" in most cases is an
insult to this concept.

[2] Long gone are the happy days when most drives would outlive their
usefulness if they managed to survive their first month of service. Now
that the hard drive manufacturers have embraced the design concepts
developed in Formula One Grand Prix race car design, it's more accurate
to describe it as a case of finding the least _unreliable_ brand or
model of drive rather than finding the most reliable.

Do you lads all reboot your machines often? I have a number of old machines
with equally old disks by various manufacturers none of which have ever
failed (fingers well crossed here!). Similarly, my employers (software
company - 100s of PCs) rarely see disk failures on desktops. The key point
is that we NEVER turn the PCs off or let the disks spin down.

Yes, I know, bad for the environment etc - but worse than having to
manufacture a new drive and dispose of the old one because on/off cycles
have killed it? Debatable (don't waste NG time on this, please!).

The most stress a disk ever gets is when you turn it on - do this more often
and they will fail more often.

Where is it physically in the machine? Even something as simply as moving
the drive down one or two slots so that air can circulate around it more
easily will help cooling no end. I find manufacturers often put all the

cooling perspective.

I have a V3 pace box with a 160 drive of which half is locked. WTF?
Why? If you install a 250 gb drive, will the box only use half of that

You can get good and bad batches of PCs, and that's more likely to
colour your opinions than anything else, even if the problem is blamed
on the wrong thing. Most PCs can be switched on and off without any
reliability problems.

Thing is... If you *do* have a bad batch - say PCs with an
under-specified power supply, or PCs that write random corruptions to
the disk, then you're most likely to discover the fault when the PC is
switched on. When you're recovering from a power blackout, that's a bad
time to discover that you've got a bunch of PC failures to deal with. So
if you have some PCs that normally do have to be left switched on,
because they are servers or whatever, then arrange a maintenance cycle
in which they are power cycled individually about once per month.

I've had something like 10 drives replaced. Often the replacements
fail too!

Actually the failure is often more subtle - the drives will seem
perfectly OK, but a quick scan with Maxtor's own disc check tools will
see a disaster coming before you do. Happily the error code it gives
you is all you need to perform an RMA on Maxtor's website. The RMA
process is excellent.. then again, it needs to be.

Well, to be fair, this was a few years ago. I don't know if it's got
better under Seagate's watch.

Maxtors, at the moment, seem to be failing more than other brands. But to be
fair I have had mdoels from all makers fail at one time or another, a few
years back IBMS 'deathstars' were all the rage. These things go in cycles.
Who knows, in a few months, it might be Seagates.

Disc space that was never 'yours' to start with, so no different to
TiVo.

Thing is... If you *do* have a bad batch - say PCs with an
under-specified power supply, or PCs that write random corruptions to
the disk, then you're most likely to discover the fault when the PC is
switched on. When you're recovering from a power blackout, that's a bad
time to discover that you've got a bunch of PC failures to deal with. So
if you have some PCs that normally do have to be left switched on,
because they are servers or whatever, then arrange a maintenance cycle
in which they are power cycled individually about once per month.


That's a very interesting point that I'd never considered. Yet another
almost unmeasurable benefit/risk comparison to throw into the mix :-).

This is on a couple of PCs that have been on all the time and only
have the disks spin down when there's been a power cut and the UPS
battery has given up (probably three or four times). I have now ended
up with more capacity on external hard drives than in all the PCs
here, just need to remember to back everything up regularly...


Beware of the following. Our company invested in some APC UPSes about 5
years ago and they came with a "test cycle". We naively assumed this would
be useful but we discovered that the "test" was to internally disconnect the
mains power, switching 100% to battery for a few seconds. Guess what
happened when we ran a test on a UPS whose battery had died - it wasn't
pleasant!
