Low-Level Formatting: This is the "true" formatting process for the disk. It creates the physical structures (tracks, sectors, control information) on the hard disk. Normally, this step begins with the hard disk platters "clean", containing no information. It is discussed in more detail here.
Partitioning: This process divides the disk into logical "pieces" that become different hard disk volumes (drive letters). This is an operating system function and is discussed in detail in its own section.
High-Level Formatting: This final step is also an operating-system-level command. It defines the logical structures on the partition and places at the start of the disk any necessary operating system files.
