ST3160815AS, this hdd it's working fine, have a Read speed of 76MB/s and Write 50MB/s, but when i check the SMART with VICTORIA and MHDD get this attributes

-Seek error rate-----------------58721051 and growing
-Hardware ECC recovered-------206385178 and growing

Both attributes on Copy or readings increases. My knowledge says when this kind or read error occurs could be:
1- a defective cable
2- dirty PCB
3- defective on the computer motherboard
4- a High Macnetic Field due a Fan or magnet close to the PCB or the cable

For this 4 posibilities i have done this:
1- change the cable, tryed 4 cables, STILL growing
2- I cleaned de PCB with an HIGHCUALITY Electronic Cleaner STILL growing
3- Tryed the 4Cables on all 6 SATA ports STILL growing
4- I removed the FANs STILL growing

This DO NOT HAPPEN with a Toshiba 750GB HDD
the HDD SMART Hardware ECC recovered and Seek error rate stays the same (Not grow)

What can I do? it is an HDD Problem? why it happen?

Thanks

It's normal.
Nothing wrong with it.
Also your drive is a 7200.10. Those are the best Seagate drives that you can possible have. It's ST-10 back from the time when Seagate did build decent drives.
As long as you don't have re-located sectors you are good to go.
Those Hardware ECC corrected errors are normal on modern drives.



Hello bro, nice to see you
Ok, i believe you, you are the boss,

I don't think you have get the big picture about what's happening with this drive.... when i say growing i don't mean 20 or 40, i mean 50000
Example:
Yesterday 11:53am -5CUBA, when i post this it had
-Seek error rate-----------------58721051 and growing
-Hardware ECC recovered-------206385178 and growing

This is TODAY 24h later
-Seek error rate-----------------62308546 and growing
-Hardware ECC recovered--------12697100 and growing :shock: WTF!

This PC just worked like 6h yesterday, on the Seek error rate whe have a diference of 3587495 on Hardware ECC recovered i don't know WTF happened!! maybe i wrote it wrong(i don't think so)

Right now i have a SO (WinXP) working on this HDD, right now i'm looking the HDTune Smart data it grows per Seconds

nice reading fzabkar BUT my knowledge on Digital sistems says when a kind of event like this happens, Speed could be afected, because most of the data proceced have to be ECC corrected, this doasen't happen on all modern drives, i have seen Seagate ST1000DM003 with this att on ZERO, and anothers with this att not on Zero but it don't grow. But mi question is simple, why is this happening? heads? bad surface?

@titokhonan, you didn't understand my article.

A raw Seek Error Rate value of 58721051 means that your drive has performed 58721051 seeks without a single error. The normalised value of this attribute would be 77 or 78.

    (-10) log10(1 / 58721051) = 77.7

The raw Hardware ECC Recovered value reflects the number of reads during the current measurement interval. When this number hits ~250 million, it rolls over to 0 and starts counting up again. The normalised value of this attribute reflects the number of errors recorded during this interval of 250 million reads.

Let's say that 30% of DM drives will die against 1% of 7200.10 drives over a short period of time

OMG


lol i knew that, on my job almost all the hdd are ST1000DM003, that the SHITTIEST hard drive i have ever seen!!! it's amazing how Seagate have a High level of sales with their shitties drives, and WD is below them on sales.

Do you have a list of Seagate and another Sellers worldwide broken drives? it's something hard to find but.... you are the imposible-man, the dude who deal with imposible task :D

Sorry i don't have any list of drives that you should avoid but i would say based on what i recieve for recovery and as damaged drives to play with that friends offer to me.......

........And of course don't use Quantum or older stuff like some WDC MCU based drives with famouse "translator" problem, etc ...

Hope this helps.


I have to make a post about this.
