Sector Gap Defined

Sectors consist of fixed blocks of storage space which usually contain 512 bytes of data. An equal number of sectors are written to each track on a floppy diskette, hard disk drive and most storage devices but the circumference of the outside tracks is much larger than the circumference of the inside tracks. For this reason, much of the storage space is wasted on some storage devices. Modern hard disk drives have eliminated much of this waste through the use of advanced data storage mapping techniques. However, on some storage devices the area between sectors on the larger tracks can be used for covert data storage. This area is referred to as sector gap. NTI does not sell tools which deal with this potential data storage area but computer security specialists should be aware of this issue when data hiding may be involved.
