Confused about error: Device: /dev/ada3, 5 Currently unreadable (pending) sectors

[Kortex]

I've seen this error on the forums before. I also see what people have done to fix it. I examined the log but I don't see where the 5 bad sectors are?

How old is your drive?

Last test was completed at 400hours.

If it's in warranty get it RMA'd

 

[Kortex]

Not very old at all. Do you see the problem :(?

I just got a

Should I shut the server off? The drive has only 300 hours on it.

Time to replace the drive.

 

[Kortex]

Thank you both for your replies! Would you mind telling me exactly what tells you I need to replace it? Is it just the pending sectors or was it something in the log or both or? The more I understand the less I will post and bug you guys :D.

 

[Stux]

5 Pending sectors means five sectors couldn't be read. So far.

This is basically a broken disk, since it is failing to read data that was written within the last two weeks.

 

[diedrichg]

As mentioned, if it's still under warranty, RMA it.

 

[danb35]

If possible, try to return it to the vendor. If you RMA it to WD, you'll get a refurbished drive in exchange. If you return it to your vendor, you should get new.

On a drive that's been in service for a while, five pending sectors wouldn't greatly worry me, but this is a new drive. I'd replace it.
