Offline uncorrectable sectors

Hello,everyone!

I've got another question regarding the log message in /var/log/messages. I have seen the following message keep logging in the messages file.

I'm not quite sure whether it is a false alarm or it is real as the server is running fine now.

Anyway,I do backup so I am not that worried.

Do you guys have any similar experiences? Please feel free to drop me a line if you do.

pending sectors is bad sectors.
look at smartctl -A /dev/sdb
you can try to remap them using MHDD or Victoria

troop,it's really weird when the hard disk is brand new and it was installed by my colleague.

By the way,what is MHDD and Victoria?

Thanks for the great help and swift reply.

Not really, look at Google’s Disk Failure Experience. With 1-year AFR(Annualized failure rates) dropping significantly from
the AFR observed in the first three months.

Well-known HDD diagnostic tools that able to make surface scan and remap bad sectors.
