Hard Drive Bad Sectors
I have a few questions on this. My understanding is that having a few bad sectors is not he end of the world. A hard drive can last years (with that said I think it is always a good idea to have two backups of important data.)
Now I have been reading in some places that if you have a few bad sectors then it is an indication that the hard drive is failing and you must buy a new one no matter what, (is this paranoid or an attempt to scare people to make money?) However in other places I am reading, for example here Bad Sector , that having a few bad sectors is normal in many cases.
Hard drives contain millions of sectors. It is very normal for some of these sectors to be bad sectors, even when the drive is first manufactured.
Thoughts on all of this?

Having a few bad sectors is one thing, but if a drive is continually gathering additional bad sectors, I'd recommend backing up as soon as possible, then replacing the drive. I usually check my own drives with S.M.A.R.T., and with the diagnostics utility provided by the hard drive manufacturer.oz
