Drive formatting is the process in which a new drive is fully prepared to store files. Formatting can be of two types, i.e. low level formatting and high level formatting. Low-level formatting marks the surface of the disk with sector markers indicating the start of a recording block, which will set the disk to the factory condition, erasing all the previous data. High-level formatting is also referred to as quick formatting that is file system format, which usually occurs during operating system installation, or when adding a new disk. You might need to format a hard drive if you are installing an operating system for the first time, trying to get rid of viruses, cleaning your hard drive to sell your computer, removing errors from your hard drive etc. When you format the hard drive that has been previously formatted to change the file system from FAT to NTFS in Windows, then it is logically termed as reformatting.
Procedure to perform disk formatting?
If you have restore-and-recovery CD (Master Setup CD) that came with the operating system, then run the CD. It will automatically perform the format, install the operating system, software and programs that came with the pre-configured computer. If you do not have master CD then you have to perform formatting manually. If you are using Windows 2000, Windows XP, Windows Vista or Windows 7, then Windows installation process offers "format your hard drive" as an option. First, ensure your computer is set to boot from CD-ROM, which is a setting in your system BIOS then insert the Windows CD and restart the computer to format. If you want to reformat the hard drive to change the file system in Windows, first select a FAT16/32 partition then right click the partition and select "Convert to NTFS". If you right click on particular drive, you can see a "Format" option available. If you click on that, you will get "Quick format" as an option and if you click "Start", it will format the drive.
Once you format hard drive, the operating system erases all bookkeeping information present on the disk, marks the bad sectors and tests the disk to make sure all sectors are reliable and creates internal address tables that is used to locate information for later added data. Following are few precautions that you must follow before you format the hard drive.
