A bad sector in computing is a disk sector on a disk storage unit that is unreadable. Upon taking damage, all information stored on that sector is lost. When a bad sector is found and marked, the operating system like Windows or Linux will skip it in the future. Bad sectors are a threat to information security in the sense of data remanence.
Read errors on a sector will not remap the sector immediately (since the correct value cannot be read and so the value to remap is not known, and also it might become readable later); instead, the drive firmware remembers that the sector needs to be remapped, and will remap it the next time it has been successfully read.

Once a legitimate user connects to the AP, the AP will eventually send out a SSID in cleartext. By impersonating this AP by automatic altering of the MAC address, the computer running the network discovery scanner will be given this SSID by legitimate users. Passive scanners include Kismet and essid jack (a program under AirJack).
