当您右键单击驱动器时，您将看到一个名为Format的选项。当您选择它时，将打开一个窗口，允许您格式化驱动器。默认为全格式^{(Full Format)}。还提供了一个选择快速格式化^{(Quick Format)}的选项。在这篇文章中，我们将尝试简要解释快速格式化和完整格式^{(Quick Format and Full Format)}之间的区别。

快速格式与全格式

快速格式化^{(Quick Format)}将重建文件系统、卷标和簇大小。

完整格式^{(Full Format)}将删除文件、重建文件系统、卷标、簇大小并扫描分区以查找坏扇区。从Windows Vista开始，完整格式会将零写入所有数据扇区。

By default in Windows Vista and later versions, the format command writes zeros to the whole disk when a full format is performed, says Microsoft.

HDD 和 SSD^{(HDD and SSD)}等存储设备需要在其上具有磁道和扇区，以便将数据写入其中。不同组数据的地址存储在文件分配表中。如果创建一个新文件，存储设备会将其存储在不同的扇区中，并将其地址写入文件分配表中。如果操作系统要工作（读取数据和写入数据），则需要访问此类文件分配表。

当您快速格式化^{(Quick Format)}驱动器时，它只是删除文件分配表并创建一个新的空白表。因此，驱动器上所有数据的地址都将被删除。只要计算机不将其他数据重写到其扇区，磁盘上的数据就会继续保留。就是这样。快速格式化^{(Quick Format)}意味着删除并创建一个全新的文件分配表，以便可以重复使用存储驱动器。它确实给人一种新鲜感，但旧数据会一直保留，直到被覆盖。如果尚未覆盖，人们可以使用其中一种数据恢复工具^{(Data Recovery Tools)}找出其中存储的内容。

与Quick Format方法一样，Full Format 方法^{(Full Format method)}也会删除并创建一个全新的文件分配表。在此之前，它会检查所有扇区以查看是否有坏扇区。如果找到，它会记下它的地址，这样数据就不会存储在那个坏扇区上。

什么是低级格式化

人们经常将低级格式化^(Formatting)与快速格式化混淆。快速格式化^{(Quick Format)}旨在建立一个新的文件分配表。而已。低级格式化由制造商在交付新存储设备之前完成。低级格式化会创建轨道和扇区，稍后快速^(Quick)和完整^(Full)格式化会使用这些轨道和扇区。

PS：我在这篇文章中使用的术语文件分配表^{(File Allocation Table)}并不完全是FAT和FAT32系统。我将其用作通用短语，以便即使是新手用户也能理解。Windows^{(Windows 10)} 10、8.1、8 和 7 使用NTFS 格式^{(NTFS format)}存储文件信息。

提示^(TIP)：如果您需要擦除驱动器，请使用第三方软件擦除存储设备^{(third-party software to wipe storage devices)}。互联网^(Internet)上有很多。其中一些也是免费的。这样你在擦除数据时会更安全。

Quick Format vs Full Format - What is the difference?

When you right-click on a drive, you wіll see an option called Format. When you select it, a window opens that allows you to format the drive. The default is Full Format. Αn option to select Quick Format is alsо available. In this post, we will try and explain the difference between Quick Format and Full Format in brief.

Quick Format vs Full Format

A Quick Format will rebuild the file system, volume label, and cluster size.

A Full Format will delete the files, rebuild the file system, volume label, cluster size & scan the partition for bad sectors. Since Windows Vista, a full format writes zeroes to all data sectors.

By default in Windows Vista and later versions, the format command writes zeros to the whole disk when a full format is performed, says Microsoft.

Storage devices like HDD and SSD need to have tracks and sectors on them so that the data can be written to them. The address of different sets of data is stored in the file allocation table. If you create a new file, the storage devices store it in different sectors and write its address in the file allocation table. Operating systems need access to such file allocation tables if they are to work (read data and write data).

When you Quick Format a drive, it simply deletes the file allocation table and creates a fresh blank one. So, the addresses of all the data on the drive are removed. The data on disk continues to stay as long as the computer does not rewrite other data to its sectors. That’s it. Quick Format means removing and creating a fresh new file allocation table so that the storage drive may be reused. It does give an air of freshness but the old data stays until written over. If not already written over, people can find out what was stored on it, using one of the Data Recovery Tools.

Like the Quick Format method, the Full Format method too, deletes and creates a fresh new file allocation table. Before doing that, it checks all sectors to see if there are any bad sectors. If found, it notes down its address so that data isn’t stored on that bad sector.

What is Low-Level Formatting

People often confuse Low-Level Formatting with quick formatting. Quick Format is meant to build a new file allocation table. Nothing more. Low-level formatting is done by manufacturers before shipping new storage devices. Low-level formatting creates tracks and sectors which are later used by Quick and Full formatting.

PS: The term File Allocation Table that I used in this post is not exactly the FAT and FAT32 system. I used it as a general phrase so that even novice users can understand. Windows 10, 8.1, 8 and 7 use NTFS format for storing file information.

TIP: If you need to wipe off the drive, use third-party software to wipe storage devices. There are plenty of them on the Internet. Some of them are free as well. That way you will be safer when wiping data.
