Green WD10EVDS giving trouble. Help needed understanding SMART info

Hi would some one please be able to help me make sense of this SMART info for my HDD?

Its a Green WD10EVDS.
Its used in a domestic satellite TV PVR. It was bought April 2011 and was working fine until Nov 2014. The PVR became slow and unresponsive. Running fsck on the HDD didn’t solve the issue. Replacing the WD10EVDS with a Seagate did.

But I’m a bit surprised that the WD is failing(?) so soon. The drive is specifically for PVRs and the PVR doesn’t get used excessively (~6 hours per day.)

I tried running the short and extended SMART tests but they abort after 10%. I don’t understand most of the SMART info below. Any help would be much appreciated. Thanks.

Hello and welcome to the community,

Try running a diagnostic using WD DLG.

Hi, thanks for the welcome.

I tried using it but it stopped after about 10% saying there were too many bad sectors. I thought the fact the drive is EXT3 formatted might have been a problem for the windows based tool ?

Diagnostic tools such as DLG and smartmontools are independent of the file system. They test the drive at the hardware level.

The following attributes confirm that your drive has numerous bad sectors.

5 Reallocated_Sector_Ct PO--CK 158 158 140 - 809
196 Reallocated_Event_Count -O--CK 199 199 000 - 1
197 Current_Pending_Sector -O--CK 193 193 000 - 1288
198 Offline_Uncorrectable ----CK 187 187 000 - 2252

The Reallocated_Sector_Ct is reporting that 809 bad sectors have been replaced with spares, while the Current_Pending_Sector attribute is telling you that 1288 bad sectors are waiting to be replaced. IIUC, the Offline_Uncorrectable attribute is reporting that 2252 sectors have been assessed as bad during background scanning.

The following attributes should ideally have raw values of 0.

1 Raw_Read_Error_Rate POSR-K 200 200 051 - 9
  7 Seek_Error_Rate -OSR-K 200 199 000 - 33
200 Multi_Zone_Error_Rate ---R-- 179 179 000 - 4221

In short your drive is very ill and should be replaced ASAP.

Hi, fzabkar. Thanks for your reply - thats just the kind of info I was hoping for.

Wow - so it’s dying. Bugger! I had hoped a reformat would fix it.

Any idea what causes all those bad sectors and read errors? Defective drive? (It doesn’t matter to WD as I’m outside warranty, but just out of interest)

For some reason I expected more life from the drive, am I misguided on that front?(used for 3.5 years at about ~6hrs/day in a PVR)
