| A division of a storage
medium such as a
hard drive
or diskette
that is a wedge shaped section of one of the circular tracks. Each arc is a
sector
that typically holds 512 bytes of data
and is given a sector number
for interleaving purposes, so the term sector may refer to the
entire single arc. The size of sectors can be customized to maximize
the storage area. For example, if a user
stores smaller files, decreasing the sector size allows more files
to fill
the space
without any leftover room.
To the right is a visual example of what the sector would
look like on a disk platter. Also see: Bad
sector, CHS, Hard disk drive
