My System Specs

Default WD Black bad sectors +1 every few months [and now gone]

Update: See last post it died

----------------------------------------
OP:

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 but no )

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.

Default 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.

Well to conclude a year-old post, the hard drive finally gave up today, when 3 reallocated sectors became 175 :P

After the post last year, I bought up a new HDD for the actual stuff, then used this hard drive for only games on my Windows machine. It probably started to croak a couple months ago when I noticed that cinematics on any games would stutter randomly. Today a game died at its menu screen, making me check the event log:

The IO operation at logical block address 0x95d1550 for Disk 2 (PDO name: \Device\0000003a) was retried.

As mentioned in my OP, no data loss, but there goes my plan to play some RTS games tonight.

I find it's always best to RMA the hard drive (if possible) as soon as you get 1 bad sector as the drive is going to die at some point or another. Plus this could mean the difference between it being under warranty or not.

I've had to RMA a few drives over the years with WD and it's always been easy and fast. Way better than Seagate.

I didn't bother trying to RMA it. I broke part of the SATA connector of my drive (cosmetic damage but it's exactly the same damage as the second last example here: WD Support / Warranty Services / End User / RMA Packaging Example Pictures)
That shows me not to build a "server" out of one of those HP home computer cases not designed to be upgraded

I'm sure there was some chance because it's not as much damage as the picture, but I just don't need another drive ATM. (Most of my stuff is stored in 3 different places - any more will get confusing!)
