2. Formatting

Formatting refers to the user-selected file system (FAT32,NTFS,EXT3,EXT4, etc.), in a specific area of the disk to write specific data, in the partition for the file allocation table, directory table, etc. for file management disk space

Writing to the file system divides the entire partition into equal-sized chunks of data, creating a File information table (I node, permissions, modification time) in the partition list. The data must be purged before writing to the file system, which was previously thought to be simply emptying the data, and now knows that emptying is just a matter of formatting to write to the filesystem.
