HDD noises

My replacement 7K60 laptop drive, which is only four months old and was
silent until this week, suddenly produces spinning (not seeking) noise
along the lines of whirr-whirr-whirr, at a frequency of (roughly, from
memory) between 1/Sec or 2/sec.


Is this something to be expected as the drive reaches a "not new"
status, or should I expect the thing to completely fail soon?


Thanks in advance for any info.

I guess you run frequent backups and know how to restore system when you get
a replacement hard disk.

Come out with it, boy, don't be shy! I can take it :)

Yeah, I'm all set. Thanks, I think.

Then run disk busy (or continuous diagnostics) for a couple of nights and
check it's SMART info, if survives. If it is still good, it might live for
another few months, no guarantees though.

I'll give it a go. Don't know if I have any control oven SMART in the
BIOS, as it is a laptop with almost nothing useful that can be changed.

If it's going to fail, let's do it now, while it's still under
guarantee.

You don't have to put it in the OVEN, just run it at normal room
temperature. Leave oven approach to MTBF scientists.

That seems to be good plan.

Had me going there for a minute - I didn't see my typo, which is quite
forgivable, given that there is only one key (G) between the N and the
R.

You sure its the hard drive ? It isnt hard to get confused about
where the noise is coming from and its actually one of the fans.

The obvious test for that is to unplug the power to the hard drive for a test.

Its also likely its a resonance/beat with another drive since
its got that 1-2/sec frequency. Hard drives in isolation dont
normally do that unless its actually a very quiet recalibrate.

Nope.

or should I expect the thing to completely fail soon?
You should with any drive, but if its actually a bearing noise,
that normally doesnt cause failure, its just a pain in the arse/ears.

See what the SMART data says, if its a
very quiet recal it should show up there.

Possible, but I don't think so. The sound is coming from the area of
the drive, plus my fan is not on all the time and is quite quiet when
it does come on.

BTW, shouldn't you be sleeping at this time, Rod? :)

Oh, you are sleeping :) It's a laptop, Rod.

Laptop. One drive, one fan, etc.

normally do that unless its actually a very quiet recalibrate.
What does this mean?

Yeah, my ears aren't the best part of my anatomy, but even I can hear
the drive now. No, actually, it's not THAT loud, but certainly audible
after all the sane people go to sleep.

I doubt I can control SMART on my laptop's BIOS. There are virtually no
useful options to change, and I don't recall seeing SMART. I'll have a
look.

Surely there is more than just one fan ?

Nope. I used to think that 9:30am meetings at work
were an absolute obscenity. I'm always up long before
that now, and now bitch about the post office not
opening before 9am when I choose to walk down
to it while its cool on stinking hot summer days |-)

Smart move not saying that previously.

Very unusual for a hard drive to have
a 1-2/sec cycle in the bearing noise.

What does what mean ? Drives recalibrate when they
cant read the data properly, basically move the heads
back to the home region and then back out to the track
that its trying to read. They dont do that for hours tho.

Surely the laptop is spinning the drive down when its not being used ?

I meant get the data with something like Everest.

98% of all meetings are obscene. A dozen or two people wasting hours,
with everybody with a mouth having something to "contribute", and
finally coming to indecision, whereas a few relevant souls could finish
off the necessities in a fraction of the time. And, given the fact that
my blood stops somewhere around my knees (when it decides to move at
all) and I'm almost perpetually cold, I'll take your stinking hot days
over Canadian or European cold anyday.

I didn't understand "quiet recalibrate". Thanks for the explanation.

Sure, and there is really no doubt at this point that the noise is from
the drive.

OK, I'll check this out.

I'm the judge here, OK? :)
Not on my keyboard.
No? What, you're using an AZERTY keyboard? On my QWERTY, there is a
diagonal line that runs, from bottom to top, N-G-R. So there is only
one letter intervening between the N and the R. True, there are several
centimeters between these keys, but only one key in the actual
straight-line path.
I'll guess that your name is not Bill.
Ah, but it is, and it comes out as "B-I-L-L" regardless of which
keyboard one uses, as long as one hits the correct keys :)

Sure, but that's an entirely different issue.

Yeah, I much prefer the hot over the cold, and if it was
possible to pull the plug on one season, I'd kill off winter.
See first line of post.
Yeah, my brain fart.

Everest SMART info says all OK.

I noticed a couple of things over the weekend. First, After I power up
the machine, the drive is quiet for a bit of time, perhaps a minute or
so, before the aforementioned noises start. Second, if I'm doing
something that uses the disk sequentially for some time (like video
encoding to a file), the noise is either diminished or changed to a
uniform pattern, rather than the rhythmic cycles I indicated in the
original post. And, FWIW, Everest reports the drive temperature as
about 43°C.

Post the actual data. The OK is just what the drive manufacturer
specifys, what matters more is reallocated bad sectors etc.

You sure its actually the hard drive ? Not easy to check with a laptop.

Not clear what that last means.

OK, that's fine.

I'll bring it with me tomorrow (I (usuallly) have the internet only in
the office).

Well, I can hear and feel the fan when it comes on, so it ain't that.
What else could it be? Also, the sound is certainly louder when I put
my ear to the surface of the laptop in the area just above the location
of the drive.
Not clear what that last means.
Do you mean you aren't clear on what I'm saying or what the symptoms
mean? In case it's the former, I suppose I'm saying that when the drive
is constantly writing, as opposed to being idle or doing things that
would cause the heads to move back and forth while seeking, the noise
seems subdued, or at least constant, rather than whirr-whirr-whirr at 1
second intervals.
