Vista - Cause of hard drive failure?

I purchased a HP Media Center PC approx 16 months ago. Shortly after I
purchased it I started getting what appeared to be an intermittent hard disk
error - the screen would suddenly go black, system would attempt to reboot
and I would get a message in the lines of "SMART FAILURE predicted... Windows
detected a hard disk problem... Immediately back up your data and replace
your hard disk drive. A failure may be imminent." Then it gives some options
to to go to the BIOS or to continue. Sometimes I can reboot immediately
(usually reboots to safe mode first, then will reboot normal), other times I
need to reattempt several times before it will actually reboot (the SMART
FAILURE screen pops up each reattempt). Once I am able to reboot it's pretty
unpredicatable when this screen will show up again... sometimes a day or so
later, other times it would be stable for a few weeks.... the reason I was
able to 'test' for a while is 1.... after the problem occurs I backed up and
removed all important data from the drive and 2... since the computer was
only a few months old HP was sending me a replacement warranty drive.

Once I recieved the replacement drive I created an image of the original
drive, copied it to the new drive and sent the 'faulty' drive back to HP. I
assumed everything was fine, but the problem started occuring about 4 months
later. So again, I made sure everything was backed up, created an image &
contacted HP for another warranty drive. Once again, everything worked
fine... for a while. Now, one year later out of the blue this 'hard drive
failure is imminent' problem is popping up again.

On each occasion I have run chkdsk and scandsk diagnostics and there are no
problems detected so that's a bit confusing to me. Is there anything else I
should be checking that could be creating the problem - perhaps a faulty
cable or something else. My computer has 2 hard drives - the primary C drive
is the one that is 'failing' and it is mounted 'vertically' on a chasis. The
second drive is mounted 'flat' on the bottom panel. Would it make any
difference if I swapped locations of the two drives???? Only thing I can
think of hear is the primary drive is in use more (since it has the OS and
all program files) and perhaps the constant spinning creates a vibration
since its mounted on a chassis, causing the cable to vibrate a little
loose????

Anyone have any thoughts?

If you are getting a SMART error then the drive is usually bad. The controller on the motherboard could be bad as well, espcially since you have had so many bad drives, which is either bad luck or your drive is bad now because your motherboard controller is bad or there may be a bad connector on your power supply. I've had a bad power supply or two in only a few of my customer's computers, the bad power supplies would just chew up hard drives and motherboards but would pass any voltagemeter test I used to diagnose the power supplies with the power supply tester which is for sale at most online e-retailers. So don't rule that out. Try a different but known good power supply first, if possible, and see if the smart errors go away.

Then confront HP, tell them that the power supply killed your motherboard and is eating hard drives every 4 months if that's the case. Beause it is really odd and unlucky to get so many bad drives. I'm guessing that the second drive may be from an older system and hasn't ever been replaced before and isn't having problems, so I think there's either a problem with the power supply connector being used or the power supply is no good and maybe the motherboard is bad. This is all hypothetical because I can't actually see your computer and diagnose it any further than what you have shared here.

I've had bad experiences with Maxtor brand hard drives. You should use the disk utility that is provided on the hard drive manufacturer's web site to determine if the hard drive is faulty.

Here are links to the big 4. Maxtor has been a subsidiary of seagate for a while now, but I'm including it since some PC makers (*HP COUGH CRAP COUGH*) like to put Maxtor branded drives into their systems still (sometimes).

Maxtor - Maxtor - External Storage, External Drive, Hard Drive
Seagate/Quantum/Maxtor - Seagate Technology
Western Digital - www.westerndigital.com
Hitachi GST & IBM (Deskstar) Hard Drives - Hitachi Global Storage Technologies

You should use a power supply tester that can test all of the connectors on your power supply and verify that the correct voltage is being supplied. Also, HP does offer a hardware diagnostic software ISO that can be burned to bootable CD-R (depends on model) that will diagnose the hardware and give a usually effective result.

Orientation of the drives doesn't matter if the drives aren't jostled around while they are spinning. I know that drives don't like to be mounted at 45 degrees and flat mounting gives the best performance results. The straight up and down mounted drives usually causes them to make noises during disk activity that is more than the flat mounted drives.

The little bit of vibration a hard drive makes during normal operation shouldn't cause it to loose it connection with either the power connector or data cable. If this is the case replace the data cable, if the connector on the power supply does not snugly fit into the power socket of the hard drive, replace the power supply, don't fart around and try to "fix" a power supply or you may end up in the hospital. Just my generic friendly warning, never alter or repair power supplies or their connectors, just replace them as directed on their affixed stickers.

I would also doubt that any connectors should be coming loose. If the drive
is vibrating that much, it's definitely got bad bearings, and would not be
able to write data reliably over the long term. Vibration that extreme would
cause the drive heads to touch down (this is called a crash) and damage them
or possibly the platter(s).

Is it possible that the environment inside your PC is just too hot?

Can you try to intall your primary drive (the one that's failing) into
another PC as a secondary? This would allow you to get an independent test -
presuming the PC you put it into has SMART monitoring.

It shouldn't really matter, but can you mount the drive horizontally when
you replace it? If it concerns you that it's vertical, you could try this. I
wouldn't recommend changing the orientation of the current drive. This can
lead to read errors, slowing performance because the drive has to re-read
data.

Only one 'disk drive computer' controlled both drives. If either
drive is defective, then the one computer will report a failure. Is
the defect in drive two but you keep replacing drive one (because
drive one controls drive two)?

Second reason for failure are completely and always defective power
supply voltages. Completely defective power supply can boot a
computer. The naive then assume the power supply is good. Power
supply causes strange things to happen once every month. Does that
sound like your computer? 'Sound' means nothing. Again, the numbers.
Voltage measurements are the only way to identify or eliminate that as
a reason for a failure.

Heat is not a problem. Your computer must be in love when a room is
100 degrees F. A computer that is failing in a 70 degree room does
not have a heat problem. It has a hardware problem. How to find a
completely defective machine? Operate it even in a 100 degree room.
If it fails, a hardware problem probably exists - another reason why
more responsible computer manufacturers provide comprehensive hardware
diagnostics - to find that failure even when heat makes the failure
easier to find..

Step back. Is your problem with hardware or software? Windows does
little to find hardware failures. Windows works around hardware
failures - does everything possible to ignore those problems. However
Windows also has system (event) logs so that months after a problem
occurs, then a hardware guy can identify the problem. What (exactly
letter by letter) does each failure message in those logs say? Just a
few suggestions that would go after a problem rather than its
symptoms.

For hardware diagnostics, you'll need to know who manufactured the hard disk
(Western Digital, Seagate, etc). Then you may be able to get diagnostices
from their site.
