Question: what is the purpose of high level and low level formatting

title: Disk storage
text: The information is sent from the computer processor to the BIOS into a chip controlling the data transfer . This is then sent out to the hard drive via a multi-wire connector . Once the data is received onto the circuit board of the drive , they are translated and compressed into a format that the individual drive can use to store onto the disk itself . The data is then passed to a chip on the circuit board that controls the access to the drive . The drive is divided into sectors of data stored onto one of the sides of one of the internal disks . An HDD with two disks internally will typically store data on all four surfaces .
