Not true. The book block is an area on the disk itself to which the
bootstrap code in the BIOS passes control after reaching the end of its own
code. Often there is more than one boot block on the disk so that in the
event one is lost, the disk is still bootable, but that depends on the
operating system.

Nonetheless, a repartition of the disk erases the prior boot block and a new
format restored a new copy, so DIamontina is wrong as well.
