Detailed explanation-1: -The size of the sectors is 512 Byte. Solution: The capacity of one side of a disk = number of cylinders ∗ Number of sectors per track (spt) ∗ bytes per sector (block). Each disc has two surfaces. This means that both surfaces of a disk together have a capacity of 859, 815, 936 Byte.
Detailed explanation-2: -On a disk that uses 512-byte sectors, a 512-byte cluster contains one sector, whereas a 4-kibibyte (KiB) cluster contains eight sectors. A cluster is the smallest logical amount of disk space that can be allocated to hold a file.
Detailed explanation-3: -The first 512 bytes on a hard drive–aka Sector Zero–contain the Master Boot Record (MBR). The MBR contains the boot code and the partition table.
Detailed explanation-4: -Usually, one sector of a hard disk drive or floppy disk can hold 512 bytes of information. This standard was established in 1956. In the 1970s, larger sizes such as 1024 and 2048 bytes were introduced to accommodate larger storage capacities.
Detailed explanation-5: -Because the maximum number that can be represented by using 32 bits is 4, 294, 967, 295, it translates to 2.199 TB of capacity by using 512-byte sectors (approximately 2.2 TB).
