The ability to "zero" all data (multi-pass formatting) on a disk was not added until Mac OS X 10.2.3. [5] Further changes introduced in Mac OS X Tiger , specifically version 10.4.3, allowed Disk Utility to be used to verify the file structure of the current boot drive.
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
