The bytes of each sector of the hard disk are 512. A sector refers to an area divided on a disk. Hard disk reading and writing take sectors as the basic unit. Each track on the disk is divided into several arc segments, and these arc segments are the sectors of the disk.
Sector is the basic unit for disk storage data. The size of each sector is generally 512 bytes.

Sector refers to the area divided on the disk. Each track on the disk is divided into several arc segments, and these arc segments are sectors of the disk. Sectors are the basic unit for hard disk reading and writing.
Each side of the disk is divided into many tracks, which are concentric circles on the surface. The closer to the center, the smaller the circles. Each track is divided into equal parts in units of 512 bytes, called sectors. In the parameter list of some hard disks, you can see parameters describing the number of sectors for each track. It is usually identified by a range. For example, 373~746, which means that the outermost track has 746 sectors and the innermost track has 373 sectors. Therefore, it can be calculated that the capacity of the tracks is from 186.5KB to 373KB (190976B--381952B ).
