Speccy says 5400rpm HDD, suppose to be 7200

[Hitzy]

I'm not sure if it was just misinformation on Bestbuy's description, or Speccy reading it wrong, but the refurb HP Pavilion Slimline s5610f I just bought was suppose to have a 7200rpm HDD.

These are the specs from HP http://h10025.www1.hp.com/ewfrf/wc/document?docname=c02479710&cc=us&dlc=en&lc=en&jumpid=reg_R1002_USEN#N455

Here is the BB description http://www.bestbuy.ca/en-CA/product/hewlett-packard-hp-pavilion-slimline-desktop-featuring-amd-athlon-ii-250-dual-core-processor-s5610f-refurbished-s5610f/10174489.aspx?path=5e99fd727471c6600371ada914375cf8en02

 

I looked around and everything points to the WDC WD64 00AAKS-65Z7B0 SATA Disk Device as being 7200rpm. Speccy also lists it as a 2mb cache which I don't think is correct either, but I'm not too sure.

 

Any help would be appreciated.

Who refurbished this, HP themselves or a BestBuy technician ?

 

If a 5400 rpm drive was fitted by mistake instead of 7200 rpm in a normal production run

that mistake should have been detected and rectified by quality control before they were shipped.

A one-off at a time refurbishment would not be subject to the same quality control. Accidents happen.

 

I suggest trying an alternative to Speccy which may confirm you were sold a dud.

 

It might be worth finding out what is meant by

09 Power-On Hours (POH) 100 (100) Data 000000001B

and

C7 UltraDMA CRC Error Count 200 (177) Data 0000000019

 

I think my drive is much older and apparently in much better condition with

09 Power-On Hours (POH) 091 (091) Data 0000001AA0

and

C7 UltraDMA CRC Error Count 200 (200) Data 0000000000

HP did the refurb, I tried HD Tune but it doesn't give me the RPM, it's just blank in that section. It does give me a warning in one section, I'll post a screen shot later today.

I'll try a couple other programs and see what I can find out and report back.

Ok, is this warning of any concern? First time I have ever really looked at these specs on a HDD

[Alan_B]

A Cyclic Redundancy Checksum is used to test whether a block of data is free of corruption,

I would guess that if an error is detected the transfer should be repeated.

I do not know if that might involve waiting for the disc to rotate and track seek to re-read the raw magnetic data and start again.

 

"Things can only get better" - or can they ?

 

I would guess that much of your computer is second hand and only the broken bits were replaced.

 

I have a WDC 640 GB drive with the same seek error rate as you

07 Seek Error Rate 100 (253) Data 0000000000

I would guess the "Worst" (253) is so much bigger than the "Current" 100 because of a special situation with WDC drives,

perhaps they count fruitless seeks whilst they are still spinning up from standstill.

 

C2 Temperature 118 (109) Data 000000001D is your temperature

C2 Temperature 120 (111) Data 000000001B is mine

That looks OK to me

 

Apart from those all my "Worst" and "Current" numbers perfectly match and indicate consistent repeatable operation.

Your numbers suggest inconsistent non-repeatable operation.

 

I would guess that underneath a nice new shiny paint job you have what car dealers would call a "cut and shut" beast,

and the mileometer has been wound back to zero.

Bad sectors have been relocated to make the HDD usable. I guess that may give bad speed of access.

 

Your computer may give you many happy years of use - but there are other possibilities.

 

I have no recent hands-on experience to know how this will pan out for you, so continue to seek better qualified advice.

 

I do strongly recommend that you consider whether you are happy to re-install Windows on a new HDD (assuming you have the installation discs).

If not then it may save grief if you use partition imaging backup software and prepare a Boot Recovery CD.

I use Macrium which has saved me twice this year from Windows Updates that crashed my system and made it unbootable.

 

People with Boot recovery CD's rarely need them.

Others are less fortunate.

Thanks a lot for the info. I tried yet another monitoring program, and got different numbers again in some of the fields, and the warning from HD Tune shows nothing on Smart Check. At this point I'm not too worried about it, I did an error scan with HD Tune and there were none,

HD Tune reads the drive correctly, showing 16mb buffer, doesn't show the rpm but shows it as 86mb/s which seems correct for a 7200rpm hdd. Not sure why speccy doesn't read it correctly, but thanks for the info!
