HM160hc Reallocated Sector Count Warning

So today i got back a dv1000 from someone who had bought it from me because of the charger was working ( minor problem all ready fixed ) while i had it i decided to check hdtune and such and i got this error under health. Is this anything to be worried about the harddrive isnt even over 200 hours.

 

If that value is correct, then yes, you should worry. That means that your hdd is suffering from bad sectors...

However that may not be an accurate value as in the case of "Temperature". Then there is no need to worry...

That doesnt mean the drive has bad sectors. It basically means that the drive skipped reading a file. This could have happened when say your friend picked up your system and ran down the stairs with your system on, while it was copying files. All it means is that it tried opening something from a sector and failed, so the drive had to move it to a spare sector in reserve in order to open it.
The threshold is 10, and your at 95, so your drive is fine.
I wouldnt worry about it much at all.

No, you're incorrect.



Usual a hard drive has like 256 to 1024 spare sectors to use, so, like 50 of them that couldn't be used isn't much.

AFAIK, "data" is the actual value of how many it has reallocated.

I have 29 of them on my WD3200BEKT, and it doesn't mean anything special according to me, nor WD themselves.

So this means that "re-allocation" of sectors is because of bad sectors. Otherwise why would the HDD re-allocate the healthy sector from somewhere else which will cause performance loss?

Yes, it's because of bad sectors, but every HDD has alot of spare sectors so you can have hundres reallocated without a problem.
It's only when you get up to several hundred reallocated sectors that you can even notice performance drops (as those sectors that went bad are on the spare end of the HDD which wil get the head to move over there instead of reading where the bad sector was).

It's nothing to worry about (as in the drive will NOT die). Worst case scenario is that performance drops, and that is when you have a huge count. It's only when you're near the max limit of spare sectors used that you should worry. All HDD's usualy get bad sectors from time to time, nothing uncommon at all, that's why the manufacturers created spare sectors to resolve the issue when getting them.

EDIT: And i think K-TRON is thinking of "raw read error rate" or something else. Because reallocated secotors = bad sectors

 

I was just trying to explain how I would think the error would appear. Maybe my example was not very good

I know exactly what you meant But it seems ramgen didn't

 

To be honest, this error also appeared on my Samsung HM160HC drive around 1300hrs of use. It hasnt caused any problems in the last month or two that the error came up. I dont think it will cause any problem.

Hehe

I have 3316 power on hours on my WD3200BEKT as we speak I have my laptop running 24/7 hehe. And i got 29 of those reallocated sectors since a week ago Haven't had a problem with my WD3200BEKT though and the performance is still at it's sweet spot (71MB/s average sequential read)


Congrats on 5900 while i'm coming close to 1000
