Samsung HM640JJ wont stop spinning?

Hi,
I recently bought a Dv6t SE computer with i5-580,8gb ram,w7 home, and a samsung hm640jj 640gb hard drive.

When i ran NFS: Hot Pursuit the other day, my computer started working hard (GPU and HDD), and when i closed it, they wouldn't stop, and i couldn't even change my switchable graphics until i restarted.
The gpu went back to normal (only when playing games or watching movies it started making effort), but the samsung drive haven't stop spinning since than.
Am I imagining?
It seems like it makes the system run hotter since even under normal usage (100% brightness, wifi off, web browsing with mobile broadband) the fan is working and i can hear it and it emits heat.
I can feel the drive spinning non stop under my left palm as if i'm always copying something, and there's even a slight vibration all over the notebook.
It doesn't look like it's windows related, cuz it happens when im in bios settings as well, and samsung say they don't need firmware updates so there's nothing in that area.
what should i do?

 

Hard drives are always spinning.

What temperatures are you getting?

Use HDtune PRO or Performance monitor to monitor the Disk I/O and usage

 

Corrected.

Hard drives will be noticeably louder when copying files for obvious reasons. HP has a diagnostic utility, try running that on the hard drive if you are worried about something going wrong. If it produces a failing result you need to test it again with a known good drive.

Fans should be on with your kind of machine, you probably have like 5470 or 5650 graphics, so it will output heat under heavy load and needs proper cooling.

 

Being a little nit-picky, don't you think? ...

OP:

Download HD Tune 2.55:
HD Tune website
Run it and go to the Health tab, see what the overall status is.

If the hard drive light is on, something is taking up your hard drive's I/O; what it is at this point I don't know. With 8GB of RAM you should not be running low on memory; press Ctrl+Alt+Esc to open up the Task Manager; go over to the Performance tab and find out how much memory is being used.

We need more info to figure out what the problem is. Tell us more about what programs you have installed and running (antivirus, etc). Be specific as possible.

 

Sorry forgot to add /sarcasm.

By the way did HP ship it out with that 640 GB Samsung or did you buy it after the fact?

 

was shipped with it

Charles, I told you it happens when im in the bios menu, so i really don't think it's a task related issue.

HD Tune Pro sees my HD as 30 degrees currently, 45 under heavy load.
In the health tab i see 4 failures on Calibration Retry Count but i looked it over and it seems normal for this drive, everything else is good, and the benchmark looks fine.
Maybe it's the vibration that makes me think something's wrong.
I read reviews saying it's a very well built drive, quite fast and doesn't vibrate much. it seems like if i press down the bottom left part of the laptop (aluminum casing) the vibration is not noticable all over the laptop.
I mean even now when the lid is closed and the laptop is docked in my room and all im doing is browsing this forum, putting my hand over any part of the lid i feel a the vibration.
too scared to open it up to see if its well held:<

 

Most new HP DV X series notebooks have the HDD ProtectSmart and have the new style HDD caddy with 4 rubber nubs to reduce vibration. You need to remove the battery to get the HDD cover off usually.

Did you run the HP diagnostics yet?

 

I, uh, wouldn't exactly trust HDDTune's diagnostic.

And yes, my HM640JJ is working perfectly.

 

it doesn't vibrate/noisy?
what is the hp diagnostics tool you are talking about? i removed most of the bloatware... kept some though.

 

Don't trust HDTune's SMART checker--at least for the HM640JJ--but the health test should be a good indicator. CrystalDiskInfo is a good, reliable SMART checker.

Noise wise, it isn't bad at all. I can't detect noticeable vibration, either.
