These platters have two sides are made up of tracks, sectors, and clusters. a cluster is a group of sectors, and a sector divides tracks into pie shaped sections. each cluster, sector, and track is numbered in order to help the computer quickly locate where specific stored data is. for example, data can be saved to side 2, sector 1, track 5.
Hard Disks Sections within each track are called sectors. a sector is the smallest physical storage unit on a disk, and is almost always 512 bytes (0.5 kb) in size. the figure below shows a hard disk with two platters. parts of a hard drive. the structure of older hard drives (i.e. prior to windows 95) will refer to a cylinder head sector notation. a. Cylinder head sector (chs) is an early method for giving addresses to each physical block of data on a hard disk drive. it is a 3d coordinate system made out of a vertical coordinate head, a horizontal (or radial) coordinate cylinder, and an angular coordinate sector. head selects a circular surface: a platter in the disk (and one of its two. 1. what is sector? in computer disk storage, a sector is a part of a track on a magnetic disk or optical disc. each physical sector is made up of two basic parts, the sector header area and the data area. it serves as the smallest storage unit of a hard drive, where each sector stores a fixed amount of user accessible data. When a hard disk undergoes a low level format, it is divided it into tracks and sectors. this low level format only happens once in the drive’s life before it leaves the manufacturer’s factory. all subsequent formatting of hard drives derive from this initial low level format, which contains information on tracks, sector layout, defect.

Disk sector. in computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. for most disks, each sector stores a fixed amount of user accessible data, traditionally 512 bytes for hard disk drives (hdds), and 2048 bytes for cd roms, dvd roms and bd roms. [1] newer hdds and ssds use 4096 byte (4 kib) sectors. To know the cylinder head sector well, the basic structure of hard disk drive must be introduced. as we all know, each hard disk drive consists of platters and read write heads. the number of platters is related to the capacity of a hard drive. each platter is divided into tracks that are concentric circles. the read write heads read and write.
