Help interpreting smart error

[Danieluwe]

Hi,

 

Just fitted a new WD EARS 2TB drive into my server,

 

On preclear transfer rates drop from 100MB/s to 5MB/s,

 

I did a short smart test and found that although it shows as passed there was 1600 errors showing as far as I can tell it is the same error repeated over and over,

 

Can anyone interpret this result for me to see if its terminal or not,

 

Many thanks in advance

 

 

Error 1670 occurred at disk power-on lifetime: 5 hours (0 days + 5 hours)

  When the command that caused the error occurred, the device was active or idle

.

 

  After command completion occurred, registers were:

  ER ST SC SN CL CH DH

  -- -- -- -- -- -- --

  01 51 08 20 63 28 ea  Error: AMNF 8 sectors at LBA = 0x0a286320 = 170418976

 

  Commands leading to the command that caused the error were:

  CR FR SC SN CL CH DH DC  Powered_Up_Time  Command/Feature_Name

  -- -- -- -- -- -- -- --  ----------------  --------------------

  c8 00 08 20 63 28 ea 08      03:33:15.013  READ DMA

  ef 10 02 00 00 00 a0 08      03:33:15.013  SET FEATURES [Reserved for Serial A

TA]

  ec 00 00 00 00 00 a0 08      03:33:15.009  IDENTIFY DEVICE

I can't say much about the actual error as I have not seen that particular one before, but the symptoms you're experiencing certainly point to a failed drive.

 

You shouldn't have 1600 errors during a preclear on a drive with 5 hours on it, and the fact that the transfers end up at 5MB/s indicate that something is clearly wrong.  I'd wait to see if someone knows for sure, but it certainly looks like it's defective.

Thanks for the reply, I was thinking the drive was DOA but hoping that as it was the same error repeated it may have been salvageable,

 

Never mind, it will be my 2nd RMA out of 6 drives!
