Explanation

A bad sector is a damaged or defective portion of a hard disk drive (or other storage media) where reliable read or write operations can no longer be performed. Bad sectors can result from physical damage (hard bad sectors) or data corruption/magnetic degradation (soft bad sectors). The operating system detects and marks these areas to prevent data from being written to them. 'Lost sector,' 'empty sector,' and 'unused sector' are not standard technical terms for damaged disk areas - 'bad sector' is the correct and universally recognized term in disk storage technology.
