bad sector |

A segment of disk storage that cannot be read or written because of a physical problem in the disk. Bad sectors on hard disks are marked by the operating system and bypassed. If data are recorded in a sector that becomes bad, file recovery software, and sometimes special hardware, must be used to restore it. |

| Generally speaking, in the process of disk array recovery all sectors of the remnant hard disks will be read from top to bottom, that is to say all bad sectors in these hard disks will be found and accordingly create corresponding "shadow sections". All of the data stored in the drive are completely intact, and not a single bad sector was found. The flash memory chip itself will detect and replace any bad sector automatically. |
