Difference between Low-level formatting and High level formatting
This is short post to tell the basic differences between different types of formatting to the noobs.
Low-level formatting happens at the factory where the disk is manufactured.Low level formatting divides the blank surface into Cylinders,Heads and Sectors.It also maps any physically defective sectors on the drive and does some fine tuning.
High-level formatting prepares a logical drive for use with particular Operating system by establishing a file system on the drive that the OS can support.There are many file systems such as FAT16,FAT32,NTFS.Ill cover these file systems in detail in upcoming posts.
The formatting done by end user is often reffered as High-level formatting.I think many of you have formatted your HDD and USB a zillion times.Do u remember, there is another option called quick format.If you check this option and start formatting it formats instantaneously.Have you wondered why this formatting happens at a rapid pace.This is due to the fact that it doesn't check for badsectors in Quick-format mode.
