Hi Guys,

So I just added a Seagate 5900 RPM 2Tb drive and ran the pre-clear script. Here is a snippet from run #3:

 

 

      Raw_Read_Error_Rate =        119    117          6        ok                        229552552

      Spin_Retry_Count =              100    100        97        near_thresh        0

      End-to-End_Error =                100    100        99        near_thresh        0

      Airflow_Temperature_Cel =    64      65          45        near_thresh      36

      Temperature_Celsius =          36      35            0        ok                        36

      Hardware_ECC_Recovered =  37      31            0        ok                        229552552

 

 

No SMART attributes are FAILING_NOW

 

 

Is this a bad drive (or soon to be one) or am I just being paranoid?

preclear_finish__5YD0SXND_2012-03-18.txt

preclear_rpt__5YD0SXND_2012-03-18.txt

Anyone? Just need to know if I should return the drive or keep it. Please help.

The key SMART lines to look at are:

 

  5 Reallocated_Sector_Ct  0x0033  100  100  036    Pre-fail  Always      -      0

197 Current_Pending_Sector  0x0012  100  100  000    Old_age  Always      -      0

198 Offline_Uncorrectable  0x0010  100  100  000    Old_age  Offline      -      0

 

And they all look good, so no issues with bad blocks.  The line that probably had you concerned was:

 

 

  1 Raw_Read_Error_Rate    0x000f  119  100  006    Pre-fail  Always      -      229552552

 

The raw value looks scary, but this is one of the (many) SMART fields where the interpretation of the RAW value is manufacturer-specific and undocumented so no one knows what it really means.  The values that are provided for the user are the normalized numbers in the VALUE, WORST and THRESH columns and in this case your drive's current 119 is way above the bad drive threshold of 006 (which in the weird world of SMART is a good thing) so you don't need to worry.

On the other hand, although all the other SMART parameters look great, there is one "normalized" value that is getting closer to its affiliated failure threshold, but still far from it.:

 

Hardware_ECC_Recovered =  37      31            0        ok                        229552552

 

All drives have hardware error-correcting.  The failure threshold for yours is 0, the normalized value is 37.  Typically a drive starts with 100 as the initial "normalized" value, so your drive has corrected its share of hardware errors.

Thanks for the help. I guess I will keep it and cross my fingers.
