New 1001FALS with strange SMART

[Marsellos]

Hello!

Two days ago I have change my 1001FALS bacause off warranty issue in lockal store.

I recieve another one 1001FALS with the date of manufacture on sticker 12/03/2012

After installing the HDD I checked SMART and I was very much surprised to find that the parameter 09 Power-on Time Count = 5260 hours…another parametrs are clear like on new HDD.

WD support dont give me the answer yet, but I dont understand how It possible. This is a very misunderstood…

This HDD could not work out as much from 12/03/2012.

Sticker on current HDD is full white without black stripes and name Caviar Black.

Can I require the replacement of the drive???

Please explain to me the situation.

Please install hard disk sentinel and see how many time it says

uh, are you sure that it says the date of manufacture is 12/03/12?  does that mean march 12, or december 3?  if it says december 3, then you might have a counterfeit drive.  not only that, but my caviar black, manufacture in mar 2012, has a yellow part at the bottom of the label.   I don’t know…

Sorry, date on sticker is 6 MAR 2012
I put the photo to first post.

That’s very suspicious. As you say, 5260 hours works out to be just over 7 months, so even at 24/7, a drive couldn’t possibly have racked up that many hours since March.

Could we see the label on the drive?

Have you consulted WD’s online warranty checker?

Can you show us the component side of the PCB? The date codes on the chips (YWW/YYWW) will tell us their Year and Week of manufacture. There will also be a WWYY date code on the PCB.

Can you tell us the 2060-xxxxxx or 2061-xxxxxx number on the PCB? This will tell us whether you have a Black or Green drive.

Can you upload a HD Tune read benchmark graph? This will tell us whether your drive spins at 7200RPM or 5400RPM.

Sorry for my delayed reply. I couldn’t see your images until they were approved.

The R/N number on the label (701567) matches the number on the PCB artwork and sticker (2060-701567 and 2061-701567). A little Googling also confirms that this PCB number matches the WD1001FALS (and WD1002FBYS / WD7501AALS / WD2003FYYS / WD7502ABYS).

I notice that the date field has a “V” at the end. I’m wondering whether this may be a refurbished or “certified repaired” drive.

Here is a similar drive with the same R/N number and an “H” suffix after the date:

Notice that it says “Recertified” above “SATA / 32MB Cache”.

Here are other drives that don’t have any obvious recertification mark:

It appears that later versions have different PCBs, ie 2060-701622 or 2060-771640.

Your HD Tune performance graph shows that the width of the band of access time data points is consistent with the rotational latency of a 7200 RPM drive, namely 8.33 msec.

The maximum sustained data transfer rate of 111MB/s is consistent with a 1TB drive that has 3 platters (ie 333MB per platter), so this makes it an older model.

You didn’t show us the component side of the PCB, so I can’t infer its age from the age of the chips. However, the spindle motor has “1138” written on the sticker, so I’m guessing that this may reflect a manufacturing date of Week 38 of 2011, but I’m not confident of that at all. Instead I have a feeling that the drive most probably dates back to 2008 or 2009.

I’m not familiar with WD’s recertified drives, but it would seem reasonable that such a drive should continue to reflect its actual Power-On Hours Count in the SMART report.

I dont really understand how I can show you the component side of the PCB.

Also drive much noisy creaked and vibrated when read and write…

But I returned this HDD to shop where I buy it and asked exchange.

I dont want some suspicious parts in my system. Let’s see how it goes…
