Physical formatting
From Wikipedia, the free encyclopedia
It is the division of hard disk platters into tracks, sectors, and cylinders. Tracks, sectors, and cylinders define the divisions in which a hard disk accesses a data from a hard disk platter. This was considered to be a dangerous task to be performed on older discs for possible surface damage.
A low level format should never be done on modern drives, as the layout is predetermined at the factory and attempting to change it could destroy the drive [1].
