SpletA controller provides a plurality of first sections with numerical information on a first scale. The plurality of first sections are obtained by dividing a recording surface of a magnetic disk in units of first memory areas in each of which a first volume of data can be written by an SMR method. The first scale corresponds to a sequence of the first sections. Splet30. maj 2016 · SECTORS:Each track is further broken down into smaller units called sectors.

Spletof the magnetic disk inside a hard drive. Each track contains a constant number of sectors, which divides each track into equal sections. A sector contains at least 512 bytes, hard disks with large sectors contain a multiple of 512 bytes. This size is the smallest unit of disk access; as a result, at least an entire sector must be read or written. foam coming out of washing machine drawerSpletWhat is the disk capacity (in MB)?
