Hard disk error

Hi! I have a server with a NFS folder. Sometimes when I try to read from it it gives me an I/O error; so I checked dmesg and I found this:

sd 3:0:14:0: [sdf] Unhandled sense code
sd 3:0:14:0: [sdf] Result: hostbyte=0x00 driverbyte=0x08
sd 3:0:14:0: [sdf] Sense Key : 0x3 [current]

end_request: I/O error, dev sdf, sector 96796742

Could be this an hd failure? How can I fix this? Or can it be related to the NFS?
How can I eventually cut out broken sectors and keep using the rest of the hd?
Thanks

Re: Hard disk error

Yeah, the kernel is quite good at picking up hard drive errors. IMHO those are indicative of a failing hard drive and unlikely to be anything to do with NFS. If I were you I would burn a copy of the Ultimate Boot CD (ultimatebootcd.com) and use the appropriate hard drive tool there to analyze (and possibly repair) your drive.

Re: Hard disk error

Might also be a problem with flaky cabling or a loose connection.

However to be on the safe side I would backup everything and give badblocks write test a go and keep an eye on the smart attributes.
