Question

Defective sectors on disks are often known as __________.

a) good blocks
b) destroyed blocks
c) bad blocks
d) None of these

Answer 1

Defective sectors on disks are known as bad blocks, which are isolated by the system to prevent data loss and managed by built-in error-correction features.

Step-by-step explanation:

Defective sectors on disks are often known as bad blocks. These are areas of the disk that are not reliable for storing or retrieving data because they have been physically or logically damaged. Disk manufacturers and operating systems typically include ways to recognize and isolate these bad blocks to prevent data loss. When a disk is formatted, a process called bad block scanning can be performed to identify and mark these sectors so that the system will not attempt to use them. Additionally, modern storage systems have built-in error correction and management techniques to handle bad blocks and maintain the integrity of the data.
