With this option, Format writes bootstrap code to the first sector of the volume (and possibly elsewhere as well). Format always writes a BIOS Parameter Block to the first sector, with or without the /S option. Another option (/Q) allows for what Microsoft calls "Quick Format". With this option the command will not perform steps 2 and 3 above.
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 ...
In the context of data storage, a filesystem block is an abstraction over disk sectors possibly encompassing multiple sectors. In other contexts, it may be a unit of a data stream or a unit of operation for a utility. [13] For example, the Unix program dd allows one to set the block size to be used during execution with the parameter bs=bytes ...
The term fixed-block architecture was created by IBM in 1979 [3] to distinguish this format from its variable-length record format. Each track is divided into fixed-length blocks, consisting of an ID field and a data field. Application programs refer to blocks by relative block number, and cannot address them by cylinder, head and record.
LBA = (C × HPC + H) × SPT + (S − 1) where C, H and S are the cylinder number, the head number, and the sector number; LBA is the logical block address; HPC is the maximum number of heads per cylinder (reported by disk drive, typically 16 for 28-bit LBA) SPT is the maximum number of sectors per track (reported by disk drive, typically 63 for ...

The command line format program also has a /p: option which writes a 0 to every addressable sector on the drive multiple times (you supply the number of passes after the /p:). However bad sectors are still a problem as there is no way to determine if the drive was successfully able to overwrite them.
