Comment 35 for bug 438136

In my experience I have one hard disk with 7 reallocated sectors and work fine (obviously).

Another case is my friend's computer, Windows has stopped working and after a analysis with Palimpsest Disk Utility (on Ubuntu 9.10 live) I've read up to 250 reallocated damage sectors. So, no false positive for me (all hard disk are Maxtor).

A clarification: Reallocated sector means that hard disk has internally isolated the sectors, so badblocks don't report errors! This is a hardware data recovery.
