I think your experience is somewhat rare. I have purchased 7 laptops
since '84 and only one of them had died after 5 years. But the hard
drive was still good. The other 6 are still running just like the day I
got them.

Your problems with hard drives sounds like they might be failing do to
vibrations. Mac laptops use high quality hard drives which can handle
shock far better than the average PC hard drive. Although Apple drives
weren't always like this. As the first iPods that used mechanical hard
drives were failing left and right. As they couldn't handle the shock of
being moved about.

I am pretty delicate with my hard drives, so they seem to be lasting
forever. I did have two out of 20 something drives fail (both in the
90's). And one failed being one week old and the other after 1 month. I
blame these being lemons from the get-go, so there you go. Oops! I also
received one DOA last year too. I almost forgot that one. ;-)

Since you have problems with hard drives failing. You might want to
checkout SSD (solid state drives). As they can handle huge amount of
vibrations and still keeps on working. They actually use them on the
Space Shuttle during launch. Then switch over to old mechanical hard
drives once they are free floating in space.

I love SSD technology. As you don't have to be delicate anymore. And you
can toss them on a chair, car seat, or whatever and not worry about the
shock or vibration damaging the drive. I have seven SSD I think now and
I think they are great. I did buy a used netbook with a seemed to be
defective SSD in it. I bought a new SSD and it has been working great
ever since. It seems they had a few bad batches from what I could figure
out. Later I discovered that defective one would work if you leave the
power on for about 90 minutes. So you could get your stuff off of it if
you needed too. ;-)

I don't know what you mean by "high quality" or where a manufacturer
would go to find large quantities of "low quality" drives to put in
their laptops.

My R51 Thinkpad has the "Active Protection" system with acceleration
sensors that retract the heads on the internal drive if it's subject to
a shock.

Many manufactures of laptops cut cost every chance they get to stay
competitive. So most laptops often doesn't get those more expensive
anti-shock featured hard drives.

Yes this is nice if you don't use SSD (solid state drives). Although SSD
are far better IMHO.

It is interesting to note my Samsung NC-10 netbook's hard drive is fully
protected with this neat feature for $329 net price. I'm fairly sure it's
a Samsung drive, but not positive. Everything inside it says Samsung on
it. You can't feel and can hardly hear the drive running with your ear to
it, unlike the vibrating monsters in my Gateways. You can hear the heads
"click" to park if you tap it and energize the sensor, which goes right
back to reading again in a fraction of a second so fast the movie buffer
doesn't run dry and balk.

Give me a break. Re: "Mac laptops use high quality hard drives which

That is just BS.

Mac laptops use the same drives ... made by Hitachi, Seagate, WD and
Fujitsu ... as PC laptops. They are no different, overall.

Let's understand what voltage we are talking about.

Both the battery and the AC adapter are simply INPUTS to a switching
power supply inside the laptop that acts like the power supply of a
desktop PC and supplies the various voltages that the laptop needs
(typically 3.3, 5.0 and maybe 12 volts). The hard drive runs off of that.

So when you say "the power supply output voltages", the power supply in
question is the INTERNAL power supply of the laptop (typically on and
part of the motherboard) and, in particular, is ***NOT*** the "AC
adapter", which, I have a strong suspicion, is what you were thinking.

That's what I'm thinking....

output of the switcher has ONE monitored winding and TWO not monitored.
One of them could be noiser than hell or way over/under voltage from a bad
rectifier or filter cap....sending the drive into hysterics....

Worth checking that drive's pinout voltages and noise....

If you believe what you are saying, then you have a case to sue Apple.
And I say go for it Barry. I love to see how far you get.

I also noticed you failed to touch on why their Mac doesn't go through
hard drives every year like their Dell does. Why is that Barry? My guess
is that you are just clueless. ;-)

I deal with hundreds of laptops a year (buying, refurbing, servicing and
selling them) and while drives do fail, the drives in most laptops will
last the life of that laptop. The situation described by the author of
the thread is simply not typical.
