Modern hard drives should map out bad sectors and hide them from the OS. 
    If there are too many, however, some bad sectors will become OS 
visible.  Dos FAT filesystems keep their own bad sector map and will 
route around them.  Linux filesystems, however, do not do this.

As a rule, by the time there are enough bad sectors in current hard 
drives that they become visible to the software, the drive is junk.  But 
it is possible to have a drive that will work fine with Windows (with a 
chunk of bad sectors identified by Scandisk) that will cause Linux to 
puke all over itself with Read/write errors.

I'm not sure off the top of my head if NTFS also re-maps bad sectors, 
but I believe it does.
