Each platter is composed of logically defined spaces called sectors and by default, most operating system (OS) sectors are configured to hold no more than 512 bytes of data. If a text file that is 400 bytes is saved to disk, the sector will have 112 bytes of extra space left overhe leftover storage that exists on a computer’s hard disk drive when a computer file does not need all the space it has been allocated by the operating system. The examination of slack space is an important aspect of computer forensics.
