Damaged portions of a disk on which no read/Write operation can be performed is known as __________.

• A. Lost sector
• B. Bad sector
• C. Empty sector
• D. Unused sector

Answer: (B)

Damaged portions of a disk that cannot be read or written are called bad sectors. A sector is the smallest unit the disk can read or write. When a sector suffers physical damage or data becomes irrecoverable, the drive marks it as bad and typically remaps it to a spare sector so it won’t be used again. This failure mode is why you might see read/write errors or drive utilities report bad sectors, and why disk firmware keeps a bad-sectors map to avoid future access to those locations. In forensic work, bad sectors can mean some data cannot be captured in an image, so investigators note and account for sectors that could not be read. The other terms aren’t the standard way to describe this condition: an empty or unused sector is simply unallocated or uninitialized data space, not damaged; a lost sector is not the conventional term in modern disk terminology.
