Hi,

I have a 160gigs samsung sata hdd, a week ago (after a power outage),
it atarted to make a "clicking" sound at random times, like it restarts

itself and so windows hangs a little while, then everything works fine.

I did not care about the clicking till today, thought it might be about

windows or something but it did happen a couple more times today.

So i backed up everything important and downloaded the tool named
"hutil" from seagate website. It is a hdd diagnose tool. And it could
not pass the "surface read test" cause of a couple of ecc errors. Does
it mean it has bad sectors? What should i do? As it works fine, isn't
it possible to mark that sectors causing errors not usable or
something? Or is it time to buy a new one?
I had no experience with hdd failures so i don't know what to do.
Please help me about this.

Thanks.
