If you just quick format, then the file data is still on the disc, only the file system structure (file names and Information where the files are stored on the disc) was deleted. You might have a disc that you want to destroy or give away.But there are cases where you might want to do a full format. ![]() So normally a quick format is what you want because it is much faster. Accessing each sector on the disc takes much more time than the quick format which only writes the blocks that contain the file system structure. Since Windows Vista a full format writes zeroes to all data sectors (see MSKB). When you say full format, then Windows XP also scans all sectors on the disc for bad sectors (see MSKB). When you format a disc, then Windows XP does a high level format, it writes a file system structure to the disc. High-level formatting might include scanning the disc for bad sectors (check if every sector can be read) and it might include writing zeroes to all data sectors on the disc. Empty in this case means that all entries in the File Allocation Table are marked as unused. For good old FAT (File Allocation Table) for example the system would write a boot sector to the first disc sector and an empty FAT to the following sectors. This means that the operating system is writing a file system structure to the disc. Second formatting is used for high-level formatting a hard disc. Normally the user can't low-level format a hard disc anymore. Nowadays the manufacturers configure the sector size (like 512 bytes or 4096 bytes) and low-level format the disc. ![]() This includes taking the disc and dividing it into small units - the blocks, which can be accessed by the operating system. The term formatting is used for different things.įirst it is used for low-level formatting a hard disc.
