WD Black bad sectors +1 every few months
 
Hi all,

Do I have a drive that's "aging" or dying?

One of my Linux boxes has a 1TB WDC WD1002FAEX, and I notice that the bad sector count goes up by exactly 1-2 every so often. "Every so often" started as ~1 year (0 to 1, then to 3), but now I'm at 3 reallocated sectors with 1 pending.

The attributes of the HDD are currently:
Code:

ID# ATTRIBUTE_NAME          FLAG    VALUE WORST THRESH TYPE      UPDATED  WHEN_FAILED RAW_VALUE
  1 Raw_Read_Error_Rate    0x002f  200  200  051    Pre-fail  Always      -      41
  3 Spin_Up_Time            0x0027  172  169  021    Pre-fail  Always      -      4383
  4 Start_Stop_Count        0x0032  098  098  000    Old_age  Always      -      2658
  5 Reallocated_Sector_Ct  0x0033  199  199  140    Pre-fail  Always      -      3
  7 Seek_Error_Rate        0x002e  200  200  000    Old_age  Always      -      0
  9 Power_On_Hours          0x0032  070  070  000    Old_age  Always      -      21937
 10 Spin_Retry_Count        0x0032  100  100  000    Old_age  Always      -      0
 11 Calibration_Retry_Count 0x0032  100  100  000    Old_age  Always      -      0
 12 Power_Cycle_Count      0x0032  099  099  000    Old_age  Always      -      1443
192 Power-Off_Retract_Count 0x0032  200  200  000    Old_age  Always      -      452
193 Load_Cycle_Count        0x0032  200  200  000    Old_age  Always      -      2205
194 Temperature_Celsius    0x0022  112  098  000    Old_age  Always      -      35
196 Reallocated_Event_Count 0x0032  198  198  000    Old_age  Always      -      2
197 Current_Pending_Sector  0x0032  200  200  000    Old_age  Always      -      1

198 Offline_Uncorrectable  0x0030  200  200  000    Old_age  Offline      -      0
199 UDMA_CRC_Error_Count    0x0032  200  200  000    Old_age  Always      -      0
200 Multi_Zone_Error_Rate  0x0008  200  198  000    Old_age  Offline      -      101

After smartd alerted me to the bad sector, I ran both SMART tests and they pass:
Code:

1  Extended offline    Completed without error      00%    21932        -
2  Short offline      Completed without error      00%    21925        -

Should I move the stuff to another hard drive? (If I lost the drive completely there'd be some :blarg: but no :censored:)

Thanks!

Typically between the file system and the disk firmware itself, it should be able to recover from failed sectors (as it seems to be doing just fine). You'll eventually start to lose capacity though I believe.

You should probably consider replacement sooner than later, or at least keep backups of important data on the drive.

Thanks for the reply! I've been looking for an excuse to try newer HDDs, so maybe this is it. Hopefully there's something good in the boxing day, or post-CES (a.k.a. January clearout).

Why does Murphy have to get my good drives... I have some very slow 160GB, 250GB, 320GB, 360GB, and 500GB drives that I'd much rather see dead than this one.

WD HDD Bad Sectors
 
I recently had the same issue. I went onto the WD site hoping the drive (WD 2TB Black) still had some warranty left on it. The skies opened and my warranty would not expire until 5 Jan 14. Did an RMA and got a brand new WD 2TB Black (latest edition) as a free upgrade replacement. Check their warranty search site - well worth it.

have a Merry Xmas.

If you need a reliable drive the wd reds are really nice got a few 3TB reds in my network.
